Array of objects that define fields to aggregate.
The data fields to group by. If not specified, a single group containing all data objects will be used.
The output field names to use for each aggregated field.
The data field for which to compute aggregate function.
Determines how size calculation should be performed, one of "content" or "padding". The default setting ("content") interprets the width and height settings as the data rectangle (plotting) dimensions, to which padding is then added. In contrast, the "padding" setting includes the padding within the view size calculations, such that the width and height settings indicate the total intended size of the view.
Default value: "content"
A boolean flag indicating if autosize layout should be re-calculated on every view update.
Default value: false
A boolean flag indicating if the domain (the axis baseline) should be included as part of the axis.
Default value: true
The formatting pattern for labels. This is D3's number format pattern for quantitative fields and D3's time format pattern for time field.
See the format documentation for more information.
Default value: derived from numberFormat config for quantitative fields and from timeFormat config for temporal fields.
A boolean flag indicating if grid lines should be included as part of the axis
Default value: true for continuous scales that are not binned; otherwise, false.
The rotation angle of the axis labels.
Default value: -90 for nominal and ordinal fields; 0 otherwise.
Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.
Default value: false.
Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.
Default value: true for axis of a continuous x-scale. Otherwise, false.
The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).
Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.
The padding, in pixels, between axis and text labels.
A boolean flag indicating if labels should be included as part of the axis.
Default value: true.
The maximum extent in pixels that axis ticks and labels should use. This determines a maximum offset value for axis titles.
Default value: undefined.
The minimum extent in pixels that axis ticks and labels should use. This determines a minimum offset value for axis titles.
Default value: 30 for y-axis; undefined for x-axis.
The offset, in pixels, by which to displace the axis from the edge of the enclosing group or data rectangle.
Default value: derived from the axis config's offset (0 by default)
The anchor position of the axis in pixels. For x-axis with top or bottom orientation, this sets the axis group x coordinate. For y-axis with left or right orientation, this sets the axis group y coordinate.
Default value: 0
A desired number of ticks, for axes visualizing quantitative scales. The resulting number may be different so that values are "nice" (multiples of 2, 5, 10) and lie within the underlying scale's range.
The size in pixels of axis ticks.
Boolean value that determines whether the axis should include ticks.
A title for the field. If null, the title will be removed.
Default value: derived from the field's name and transformation function (aggregate, bin and timeUnit). If the field has an aggregate function, the function is displayed as a part of the title (e.g., "Sum of Profit"). If the field is binned or has a time unit applied, the applied function will be denoted in parentheses (e.g., "Profit (binned)", "Transaction Date (year-month)"). Otherwise, the title is simply the field name.
Note: You can customize the default field title format by providing the [fieldTitle property in the config or fieldTitle function via the compile function's options.
Max length for axis title if the title is automatically generated from the field's description.
The padding, in pixels, between title and axis.
Explicitly set the visible axis tick values.
A non-positive integer indicating z-index of the axis.
If zindex is 0, axes should be drawn behind all chart elements.
To put them in front, use "zindex = 1".
Default value: 1 (in front of the marks) for actual axis and 0 (behind the marks) for grids.
An interpolation fraction indicating where, for band scales, axis ticks should be positioned. A value of 0 places ticks at the left edge of their bands. A value of 0.5 places ticks in the middle of their bands.
A boolean flag indicating if the domain (the axis baseline) should be included as part of the axis.
Default value: true
Color of axis domain line.
Default value: (none, using Vega default).
Stroke width of axis domain line
Default value: (none, using Vega default).

Default value: (1 by default)
The grid width, in pixels.

For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis.

Polar coordinate angle, in radians, of the text label from the origin determined by the x and y properties. Values for theta follow the same convention of arc mark startAngle and endAngle properties: angles are measured in radians, with 0 indicating "north".
12 nested properties
Color of the marks – either fill or stroke color based on mark type.
By default, color represents fill color for "area", "bar", "tick",
"text", "circle", and "square" / stroke color for "line" and "point".
Default value: If undefined, the default color depends on mark config's color property.
Note: See the scale documentation for more information about customizing color scheme.
Additional levels of detail for grouping data in aggregate views and in line and area marks without mapping data to a specific visual channel.
Opacity of the marks – either can be a value or a range.
Default value: If undefined, the default opacity depends on mark config's opacity property.
Stack order for stacked marks or order of data points in line marks for connected scatter plots.
Note: In aggregate plots, order field should be aggregated to avoid creating additional aggregation grouping.
The symbol's shape (only for point marks). The supported values are
"circle" (default), "square", "cross", "diamond", "triangle-up",
or "triangle-down", or else a custom SVG path string.
Default value: If undefined, the default shape depends on mark config's shape property.
Size of the mark.
- For
"point","square"and"circle", – the symbol size, or pixel area of the mark. - For
"bar"and"tick"– the bar and tick's size. - For

Description of this mark for commenting purpose.
The height of a visualization.
Default value:
- If a view's
autosizetype is"fit"or its y-channel has a continuous scale, the height will be the value ofconfig.view.height. - For y-axis with a band or point scale: if
rangeStepis a numeric value or unspecified, the height is determined by the range step, paddings, and the cardinality of the field mapped to y-channel. Otherwise, if therangeStepisnull, the height will be the value ofconfig.view.height. - If no field is mapped to
ychannel, theheightwill be the value ofrangeStep.
Note: For plots with row and column channels, this represents the height of a single view.
See also: The documentation for width and height contains more examples.
Name of the visualization for later reference.
A key-value mapping between selection names and definitions.
Title for the plot.
An array of data transformations such as filter and new field calculation.
The width of a visualization.
Default value: This will be determined by the following rules:
- If a view's
autosizetype is"fit"or its x-channel has a continuous scale, the width will be the value ofconfig.view.width. - For x-axis with a band or point scale: if
rangeStepis a numeric value or unspecified, the width is determined by the range step, paddings, and the cardinality of the field mapped to x-channel. Otherwise, if therangeStepisnull, the width will be the value ofconfig.view.width. - If no field is mapped to
xchannel, thewidthwill be the value ofconfig.scale.textXRangeStepfortextmark and the value ofrangeStepfor other marks.
Note: For plots with row and column channels, this represents the width of a single view.

Constants and utilities for data type
Data type based on level of measurement
A flag for binning a quantitative field, or an object defining binning parameters.
If true, default binning parameters will be applied.
Default value: false
Required. A string defining the name of the field from which to pull a data value
or an object defining iterated values from the repeat operator.
Note: field is not required if aggregate is count.
An object defining properties of the legend.
If null, the legend for the encoding channel will be removed.
Default value: If undefined, default legend properties are applied.
15 nested properties
The logarithm base of the log scale (default 10).
If true, values that exceed the data domain are clamped to either the minimum or maximum range value
Default value: derived from the scale config's clamp (true by default).
Customized domain values.
For quantitative fields, domain can take the form of a two-element array with minimum and maximum values. Piecewise scales can be created by providing a domain with more than two entries.
If the input field is aggregated, domain can also be a string value "unaggregated", indicating that the domain should include the raw data values prior to the aggregation.
For temporal fields, domain can be a two-element array minimum and maximum values, in the form of either timestamps or the DateTime definition objects.
For ordinal and nominal fields, domain can be an array that lists valid input values.
The selection property can be used to interactively determine the scale domain.
The exponent of the pow scale.
The interpolation method for range values. By default, a general interpolator for numbers, dates, strings and colors (in RGB space) is used. For color ranges, this property allows interpolation in alternative color spaces. Legal values include rgb, hsl, hsl-long, lab, hcl, hcl-long, cubehelix and cubehelix-long ('-long' variants use longer paths in polar coordinate spaces). If object-valued, this property accepts an object with a string-valued type property and an optional numeric gamma property applicable to rgb and cubehelix interpolators. For more, see the d3-interpolate documentation.
Extending the domain so that it starts and ends on nice round values. This method typically modifies the scale's domain, and may only extend the bounds to the nearest round value. Nicing is useful if the domain is computed from data and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0].
For quantitative scales such as linear, nice can be either a boolean flag or a number. If nice is a number, it will represent a desired tick count. This allows greater control over the step size used to extend the bounds, guaranteeing that the returned ticks will exactly cover the domain.
For temporal fields with time and utc scales, the nice value can be a string indicating the desired time interval. Legal values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, time and utc scales can accept an object-valued interval specifier of the form {"interval": "month", "step": 3}, which includes a desired number of interval steps. Here, the domain would snap to quarter (Jan, Apr, Jul, Oct) boundaries.
Default value: true for unbinned quantitative fields; false otherwise.
For continuous scales, expands the scale domain to accommodate the specified number of pixels on each of the scale range. The scale range must represent pixels for this parameter to function as intended. Padding adjustment is performed prior to all other adjustments, including the effects of the zero, nice, domainMin, and domainMax properties.
For band scales, shortcut for setting paddingInner and paddingOuter to the same value.
For point scales, alias for paddingOuter.
Default value: For continuous scales, derived from the scale config's continuousPadding.
For band and point scales, see paddingInner and paddingOuter.
The inner padding (spacing) within each band step of band scales, as a fraction of the step size. This value must lie in the range [0,1].
For point scale, this property is invalid as point scales do not have internal band widths (only step sizes between bands).
Default value: derived from the scale config's bandPaddingInner.
The outer padding (spacing) at the ends of the range of band and point scales, as a fraction of the step size. This value must lie in the range [0,1].
Default value: derived from the scale config's bandPaddingOuter for band scales and pointPadding for point scales.
The range of the scale. One of:
-
A string indicating a pre-defined named scale range (e.g., example,
"symbol", or"diverging"). -
For continuous scales, two-element array indicating minimum and maximum values, or an array with more than two entries for specifying a piecewise scale.
-
For discrete and discretizing scales, an array of desired output values.
Notes:
-
For sequential, ordinal, and discretizing color scales, you can also specify a color
schemeinstead ofrange. -
Any directly specified
rangeforxandychannels will be ignored. Range can be customized via the view's corresponding size (widthandheight) or via range steps and paddings properties for band and point scales.
The distance between the starts of adjacent bands or points in band and point scales.
If rangeStep is null or if the view contains the scale's corresponding size (width for x scales and height for y scales), rangeStep will be automatically determined to fit the size of the view.
Default value: derived the scale config's textXRangeStep (90 by default) for x-scales of text marks and rangeStep (21 by default) for x-scales of other marks and y-scales.
Warning: If rangeStep is null and the cardinality of the scale's domain is higher than width or height, the rangeStep might become less than one pixel and the mark might not appear correctly.
If true, rounds numeric output values to integers. This can be helpful for snapping to the pixel grid.
Default value: false.
A string indicating a color scheme name (e.g., "category10" or "viridis") or a scheme parameter object.
Discrete color schemes may be used with discrete or discretizing scales. Continuous color schemes are intended for use with sequential scales.
For the full list of supported scheme, please refer to the Vega Scheme reference.
If true, ensures that a zero baseline value is included in the scale domain.
Default value: true for x and y channels if the quantitative field is not binned and no custom domain is provided; false otherwise.
Note: Log, time, and utc scales do not support zero.
Sort order for the encoded field.
Supported sort values include "ascending", "descending" and null (no sorting).
For fields with discrete domains, sort can also be a sort field definition object.
Default value: "ascending"

15 nested properties
The logarithm base of the log scale (default 10).
If true, values that exceed the data domain are clamped to either the minimum or maximum range value
Default value: derived from the scale config's clamp (true by default).
Customized domain values.
For quantitative fields, domain can take the form of a two-element array with minimum and maximum values. Piecewise scales can be created by providing a domain with more than two entries.
If the input field is aggregated, domain can also be a string value "unaggregated", indicating that the domain should include the raw data values prior to the aggregation.
For temporal fields, domain can be a two-element array minimum and maximum values, in the form of either timestamps or the DateTime definition objects.
For ordinal and nominal fields, domain can be an array that lists valid input values.
The selection property can be used to interactively determine the scale domain.
The exponent of the pow scale.
The interpolation method for range values. By default, a general interpolator for numbers, dates, strings and colors (in RGB space) is used. For color ranges, this property allows interpolation in alternative color spaces. Legal values include rgb, hsl, hsl-long, lab, hcl, hcl-long, cubehelix and cubehelix-long ('-long' variants use longer paths in polar coordinate spaces). If object-valued, this property accepts an object with a string-valued type property and an optional numeric gamma property applicable to rgb and cubehelix interpolators. For more, see the d3-interpolate documentation.
Extending the domain so that it starts and ends on nice round values. This method typically modifies the scale's domain, and may only extend the bounds to the nearest round value. Nicing is useful if the domain is computed from data and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0].
For quantitative scales such as linear, nice can be either a boolean flag or a number. If nice is a number, it will represent a desired tick count. This allows greater control over the step size used to extend the bounds, guaranteeing that the returned ticks will exactly cover the domain.
For temporal fields with time and utc scales, the nice value can be a string indicating the desired time interval. Legal values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, time and utc scales can accept an object-valued interval specifier of the form {"interval": "month", "step": 3}, which includes a desired number of interval steps. Here, the domain would snap to quarter (Jan, Apr, Jul, Oct) boundaries.
Default value: true for unbinned quantitative fields; false otherwise.
For continuous scales, expands the scale domain to accommodate the specified number of pixels on each of the scale range. The scale range must represent pixels for this parameter to function as intended. Padding adjustment is performed prior to all other adjustments, including the effects of the zero, nice, domainMin, and domainMax properties.
For band scales, shortcut for setting paddingInner and paddingOuter to the same value.
For point scales, alias for paddingOuter.
Default value: For continuous scales, derived from the scale config's continuousPadding.
For band and point scales, see paddingInner and paddingOuter.
The inner padding (spacing) within each band step of band scales, as a fraction of the step size. This value must lie in the range [0,1].
For point scale, this property is invalid as point scales do not have internal band widths (only step sizes between bands).
Default value: derived from the scale config's bandPaddingInner.
The outer padding (spacing) at the ends of the range of band and point scales, as a fraction of the step size. This value must lie in the range [0,1].
Default value: derived from the scale config's bandPaddingOuter for band scales and pointPadding for point scales.
The range of the scale. One of:
-
A string indicating a pre-defined named scale range (e.g., example,
"symbol", or"diverging"). -
For continuous scales, two-element array indicating minimum and maximum values, or an array with more than two entries for specifying a piecewise scale.
-
For discrete and discretizing scales, an array of desired output values.
Notes:
-
For sequential, ordinal, and discretizing color scales, you can also specify a color
schemeinstead ofrange. -
Any directly specified
rangeforxandychannels will be ignored. Range can be customized via the view's corresponding size (widthandheight) or via range steps and paddings properties for band and point scales.
The distance between the starts of adjacent bands or points in band and point scales.
If rangeStep is null or if the view contains the scale's corresponding size (width for x scales and height for y scales), rangeStep will be automatically determined to fit the size of the view.
Default value: derived the scale config's textXRangeStep (90 by default) for x-scales of text marks and rangeStep (21 by default) for x-scales of other marks and y-scales.
Warning: If rangeStep is null and the cardinality of the scale's domain is higher than width or height, the rangeStep might become less than one pixel and the mark might not appear correctly.
If true, rounds numeric output values to integers. This can be helpful for snapping to the pixel grid.
Default value: false.
A string indicating a color scheme name (e.g., "category10" or "viridis") or a scheme parameter object.
Discrete color schemes may be used with discrete or discretizing scales. Continuous color schemes are intended for use with sequential scales.
For the full list of supported scheme, please refer to the Vega Scheme reference.
If true, ensures that a zero baseline value is included in the scale domain.
Default value: true for x and y channels if the quantitative field is not binned and no custom domain is provided; false otherwise.
Note: Log, time, and utc scales do not support zero.
Sort order for the encoded field.
Supported sort values include "ascending", "descending" and null (no sorting).
For fields with discrete domains, sort can also be a sort field definition object.
Default value: "ascending"

If set to auto (the default), perform automatic type inference to determine the desired data types.
Alternatively, a parsing directive object can be provided for explicit data types. Each property of the object corresponds to a field name, and the value to the desired data type (one of "number", "boolean" or "date").
For example, "parse": {"modified_on": "date"} parses the modified_on field in each input record a Date value.
For "date", we parse data based using Javascript's Date.parse().
For Specific date formats can be provided (e.g., {foo: 'date:"%m%d%Y"'}), using the d3-time-format syntax. UTC date format parsing is supported similarly (e.g., {foo: 'utc:"%m%d%Y"'}). See more about UTC time

A string or array of strings indicating the name of custom styles to apply to the mark. A style is a named collection of mark property defaults defined within the style configuration. If style is an array, later styles will override earlier styles. Any mark properties explicitly defined within the encoding will override a style default.
Default value: The mark's name. For example, a bar mark will have style "bar" by default.
Note: Any specified style will augment the default style. For example, a bar mark with "style": "foo" will receive from config.style.bar and config.style.foo (the specified style "foo" has higher precedence).
Depending on the interpolation type, sets the tension parameter (for line and area marks).

Constants and utilities for data type
Data type based on level of measurement
A flag for binning a quantitative field, or an object defining binning parameters.

15 nested properties
The logarithm base of the log scale (default 10).
If true, values that exceed the data domain are clamped to either the minimum or maximum range value
Default value: derived from the scale config's clamp (true by default).
Customized domain values.
For quantitative fields, domain can take the form of a two-element array with minimum and maximum values. Piecewise scales can be created by providing a domain with more than two entries.
If the input field is aggregated, domain can also be a string value "unaggregated", indicating that the domain should include the raw data values prior to the aggregation.
For temporal fields, domain can be a two-element array minimum and maximum values, in the form of either timestamps or the DateTime definition objects.
For ordinal and nominal fields, domain can be an array that lists valid input values.
The selection property can be used to interactively determine the scale domain.
The exponent of the pow scale.
The interpolation method for range values. By default, a general interpolator for numbers, dates, strings and colors (in RGB space) is used. For color ranges, this property allows interpolation in alternative color spaces. Legal values include rgb, hsl, hsl-long, lab, hcl, hcl-long, cubehelix and cubehelix-long ('-long' variants use longer paths in polar coordinate spaces). If object-valued, this property accepts an object with a string-valued type property and an optional numeric gamma property applicable to rgb and cubehelix interpolators. For more, see the d3-interpolate documentation.
Extending the domain so that it starts and ends on nice round values. This method typically modifies the scale's domain, and may only extend the bounds to the nearest round value. Nicing is useful if the domain is computed from data and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0].
For quantitative scales such as linear, nice can be either a boolean flag or a number. If nice is a number, it will represent a desired tick count. This allows greater control over the step size used to extend the bounds, guaranteeing that the returned ticks will exactly cover the domain.
For temporal fields with time and utc scales, the nice value can be a string indicating the desired time interval. Legal values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, time and utc scales can accept an object-valued interval specifier of the form {"interval": "month", "step": 3}, which includes a desired number of interval steps. Here, the domain would snap to quarter (Jan, Apr, Jul, Oct) boundaries.
Default value: true for unbinned quantitative fields; false otherwise.
For continuous scales, expands the scale domain to accommodate the specified number of pixels on each of the scale range. The scale range must represent pixels for this parameter to function as intended.

For point scales, alias for paddingOuter.
Default value: For continuous scales, derived from the scale config's continuousPadding.
For band and point scales, see paddingInner and paddingOuter.

For point scale, this property is invalid as point scales do not have internal band widths (only step sizes between bands).
Default value: derived from the scale config's bandPaddingInner.
The outer padding (spacing) at the ends of the range of band and point scales, as a fraction of the step size. This value must lie in the range [0,1].

-
For discrete and discretizing scales, an array of desired output values.
Notes:
-
For sequential, ordinal, and discretizing color scales, you can also specify a color
schemeinstead ofrange. -
Any directly specified
rangeforxandychannels will be ignored. Range can be customized via the view's corresponding size (widthandheight) or via range steps and paddings properties for band and point scales.
The distance between the starts of adjacent bands or points in band and point scales.
If rangeStep is null or if the view contains the scale's corresponding size (width for x scales and height for y scales), rangeStep will be automatically determined to fit the size of the view.
Default value: derived the scale config's textXRangeStep (90 by default) for x-scales of text marks and rangeStep (21 by default) for x-scales of other marks and y-scales.
Warning: If rangeStep is null and the cardinality of the scale's domain is higher than width or height, the rangeStep might become less than one pixel and the mark might not appear correctly.
If true, rounds numeric output values to integers. This can be helpful for snapping to the pixel grid.
Default value: false.
A string indicating a color scheme name (e.g., "category10" or "viridis") or a scheme parameter object.

Default value: -90 for nominal and ordinal fields; 0 otherwise.
Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.
Default value: false.
The color of the tick label, can be in hex color code or regular color name.
Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.
Default value: true for axis of a continuous x-scale. Otherwise, false.
The font of the tick label.
The font size of the label, in pixels.
Maximum allowed pixel width of axis tick labels.
The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).
Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

Defines how Vega-Lite should handle invalid values (null and NaN).
- If set to
"filter"(default), all data items with null values are filtered. - If
null, all data items are included. In this case, invalid values will be interpreted as zeroes.

Default value: -90 for nominal and ordinal fields; 0 otherwise.
Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.
Default value: false.
The color of the tick label, can be in hex color code or regular color name.
Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.
Default value: true for axis of a continuous x-scale. Otherwise, false.

If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).
Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

autosizetype is"fit"or its y-channel has a continuous scale, the height will be the value ofconfig.view.height. - For y-axis with a band or point scale: if
rangeStepis a numeric value or unspecified, the height is determined by the range step, paddings, and the cardinality of the field mapped to y-channel. Otherwise, if therangeStepisnull, the height will be the value ofconfig.view.height. - If no field is mapped to
ychannel, theheightwill be the value ofrangeStep.
Note: For plots with row and column channels, this represents the height of a single view.
See also: The documentation for width and height contains more examples.
Name of the visualization for later reference.
Defines how scales, axes, and legends from different specs should be combined. Resolve is a mapping from scale, axis, and legend to a mapping from channels to resolutions.
Title for the plot.
An array of data transformations such as filter and new field calculation.
The width of a visualization.
Default value: This will be determined by the following rules:
- If a view's
autosizetype is"fit"or its x-channel has a continuous scale, the width will be the value ofconfig.view.width. - For x-axis with a band or point scale: if
rangeStepis a numeric value or unspecified, the width is determined by the range step, paddings, and the cardinality of the field mapped to x-channel. Otherwise, if therangeStepisnull, the width will be the value ofconfig.view.width. - If no field is mapped to
xchannel, thewidthwill be the value ofconfig.scale.textXRangeStepfortextmark and the value ofrangeStepfor other marks.
Note: For plots with row and column channels, this represents the width of a single view.

38 nested properties
An interpolation fraction indicating where, for band scales, axis ticks should be positioned. A value of 0 places ticks at the left edge of their bands. A value of 0.5 places ticks in the middle of their bands.
A boolean flag indicating if the domain (the axis baseline) should be included as part of the axis.
Default value: true
Color of axis domain line.
Default value: (none, using Vega default).
Stroke width of axis domain line
Default value: (none, using Vega default).
A boolean flag indicating if grid lines should be included as part of the axis
Default value: true for continuous scales that are not binned; otherwise, false.
Color of gridlines.
The offset (in pixels) into which to begin drawing with the grid dash array.
The stroke opacity of grid (value between [0,1])
Default value: (1 by default)
The grid width, in pixels.
The rotation angle of the axis labels.
Default value: -90 for nominal and ordinal fields; 0 otherwise.
Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.
Default value: false.
The color of the tick label, can be in hex color code or regular color name.
Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.
Default value: true for axis of a continuous x-scale. Otherwise, false.
The font of the tick label.
The font size of the label, in pixels.
Maximum allowed pixel width of axis tick labels.
The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).
Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.
The padding, in pixels, between axis and text labels.
A boolean flag indicating if labels should be included as part of the axis.
Default value: true.
The maximum extent in pixels that axis ticks and labels should use. This determines a maximum offset value for axis titles.
Default value: undefined.
The minimum extent in pixels that axis ticks and labels should use. This determines a minimum offset value for axis titles.

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis.

The name of the TopoJSON object set to convert to a GeoJSON feature collection.
For example, in a map of the world, there may be an object set named "countries".
Using the feature property, we can extract this set and generate a GeoJSON feature object for each country.
The name of the TopoJSON object set to convert to mesh.
Similar to the feature option, mesh extracts a named TopoJSON object set.
Unlike the feature option, the corresponding geo data is returned as a single, unified mesh instance, not as individual GeoJSON features.
Extracting a mesh is useful for more efficiently drawing borders or other geographic elements that you do not need to associate with specific regions such as individual countries, states or counties.
If set to auto (the default), perform automatic type inference to determine the desired data types.
Alternatively, a parsing directive object can be provided for explicit data types. Each property of the object corresponds to a field name, and the value to the desired data type (one of "number", "boolean" or "date").
For example, "parse": {"modified_on": "date"} parses the modified_on field in each input record a Date value.
For "date", we parse data based using Javascript's Date.parse().
For Specific date formats can be provided (e.g., {foo: 'date:"%m%d%Y"'}), using the d3-time-format syntax. UTC date format parsing is supported similarly (e.g., {foo: 'utc:"%m%d%Y"'}). See more about UTC time
Type of input data: "json", "csv", "tsv".
The default format type is determined by the extension of the file URL.
If no extension is detected, "json" will be used by default.

Defines how Vega-Lite should handle invalid values (null and NaN).
- If set to
"filter"(default), all data items with null values are filtered. - If
null, all data items are included. In this case, invalid values will be interpreted as zeroes.

If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.
Default value: false.
The color of the tick label, can be in hex color code or regular color name.
Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label.
