Attributes

bandPaddingInneranyOf(float, ExprRef)

Default inner padding for x and y band scales.

Default value:

• nestedOffsetPaddingInner for x/y scales with nested x/y offset scales.

• barBandPaddingInner for bar marks ( 0.1 by default)

• rectBandPaddingInner for rect and other marks ( 0 by default)

bandPaddingOuteranyOf(float, ExprRef)

Default outer padding for x and y band scales.

Default value: paddingInner/2 (which makes width/height = number of unique values * step )

bandWithNestedOffsetPaddingInneranyOf(float, ExprRef)

Default inner padding for x and y band scales with nested xOffset and yOffset encoding.

Default value: 0.2

bandWithNestedOffsetPaddingOuteranyOf(float, ExprRef)

Default outer padding for x and y band scales with nested xOffset and yOffset encoding.

Default value: 0.2

barBandPaddingInneranyOf(float, ExprRef)

Default inner padding for x and y band-ordinal scales of "bar" marks.

Default value: 0.1

clampanyOf(boolean, ExprRef)

If true, values that exceed the data domain are clamped to either the minimum or maximum range value

continuousPaddinganyOf(float, ExprRef)

Default padding for continuous x/y scales.

Default: The bar width for continuous x-scale of a vertical bar and continuous y-scale of a horizontal bar.; 0 otherwise.

maxBandSizefloat

The default max value for mapping quantitative fields to bar’s size/bandSize.

If undefined (default), we will use the axis’s size (width or height) - 1.

maxFontSizefloat

The default max value for mapping quantitative fields to text’s size/fontSize.

Default value: 40

maxOpacityfloat

Default max opacity for mapping a field to opacity.

Default value: 0.8

maxSizefloat

Default max value for point size scale.

maxStrokeWidthfloat

Default max strokeWidth for the scale of strokeWidth for rule and line marks and of size for trail marks.

Default value: 4

minBandSizefloat

The default min value for mapping quantitative fields to bar and tick’s size/bandSize scale with zero=false.

Default value: 2

minFontSizefloat

The default min value for mapping quantitative fields to tick’s size/fontSize scale with zero=false

Default value: 8

minOpacityfloat

Default minimum opacity for mapping a field to opacity.

Default value: 0.3

minSizefloat

Default minimum value for point size scale with zero=false.

Default value: 9

minStrokeWidthfloat

Default minimum strokeWidth for the scale of strokeWidth for rule and line marks and of size for trail marks with zero=false.

Default value: 1

offsetBandPaddingInneranyOf(float, ExprRef)

Default padding inner for xOffset/yOffset’s band scales.

Default Value: 0

offsetBandPaddingOuteranyOf(float, ExprRef)

Default padding outer for xOffset/yOffset’s band scales.

Default Value: 0

pointPaddinganyOf(float, ExprRef)

Default outer padding for x and y point-ordinal scales.

Default value: 0.5 (which makes width/height = number of unique values * step )

quantileCountfloat

Default range cardinality for quantile scale.

Default value: 4

quantizeCountfloat

Default range cardinality for quantize scale.

Default value: 4

rectBandPaddingInneranyOf(float, ExprRef)

Default inner padding for x and y band-ordinal scales of "rect" marks.

Default value: 0

roundanyOf(boolean, ExprRef)

If true, rounds numeric output values to integers. This can be helpful for snapping to the pixel grid. (Only available for x, y, and size scales.)

useUnaggregatedDomainboolean

Use the source data range before aggregation as scale domain instead of aggregated data for aggregate axis.

This is equivalent to setting domain to "unaggregate" for aggregated quantitative fields by default.

This property only works with aggregate functions that produce values within the raw data domain ( "mean", "average", "median", "q1", "q3", "min", "max" ). For other aggregations that produce values outside of the raw data domain (e.g. "count", "sum" ), this property is ignored.

Default value: false

xReverseanyOf(boolean, ExprRef)

Reverse x-scale by default (useful for right-to-left charts).
