altair.theme.LegendConfigKwds#

class altair.theme.LegendConfigKwds#

altair.LegendConfig TypedDict wrapper.

Parameters:
aria

A boolean flag indicating if ARIA attributes should be included (SVG output only). If false, the “aria-hidden” attribute will be set on the output SVG group, removing the legend from the ARIA accessibility tree.

Default value: true

clipHeight

The height in pixels to clip symbol legend entries and limit their size.

columnPadding

The horizontal padding in pixels between symbol legend entries.

Default value: 10.

columns

The number of columns in which to arrange symbol legend entries. A value of 0 or lower indicates a single row with one column per entry.

cornerRadius

Corner radius for the full legend.

description

A text description of this legend for ARIA accessibility (SVG output only). If the aria property is true, for SVG output the “aria-label” attribute will be set to this description. If the description is unspecified it will be automatically generated.

direction

The direction of the legend, one of "vertical" or "horizontal".

Default value:

  • For top-/bottom-orient``ed legends, ``"horizontal"

  • For left-/right-orient``ed legends, ``"vertical"

  • For top/bottom-left/right-orient``ed legends, ``"horizontal" for gradient legends and "vertical" for symbol legends.

disable

Disable legend by default

Default value: 200

gradientHorizontalMinLength

Min legend length for a horizontal gradient when config.legend.gradientLength is undefined.

Default value: 100

gradientLabelLimit

The maximum allowed length in pixels of color ramp gradient labels.

gradientLength

The length in pixels of the primary axis of a color gradient. This value corresponds to the height of a vertical gradient or the width of a horizontal gradient.

Default value: 200.

gradientOpacity

Opacity of the color gradient.

gradientStrokeColor

The color of the gradient stroke, can be in hex color code or regular color name.

Default value: "lightGray".

gradientStrokeWidth

The width of the gradient stroke, in pixels.

Default value: 0.

gradientThickness

The thickness in pixels of the color gradient. This value corresponds to the width of a vertical gradient or the height of a horizontal gradient.

Default value: 16.

gradientVerticalMaxLength

Max legend length for a vertical gradient when config.legend.gradientLength is undefined.

Default value: 200

Min legend length for a vertical gradient when config.legend.gradientLength is undefined.

Default value: 100

gridAlign

The alignment to apply to symbol legends rows and columns. The supported string values are "all", "each" (the default), and none. For more information, see the grid layout documentation.

Default value: "each".

labelAlign

The alignment of the legend label, can be left, center, or right.

labelBaseline

The position of the baseline of legend label, can be "top", "middle", "bottom", or "alphabetic".

Default value: "middle".

labelColor

The color of the legend label, can be in hex color code or regular color name.

labelFont

The font of the legend label.

labelLimit

Maximum allowed pixel width of legend tick labels.

Default value: 160.

labelOffset

The offset of the legend label.

Default value: 4.

labelOpacity

Opacity of labels.

labelOverlap

The strategy to use for resolving overlap of labels in gradient legends. If false, no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used. If set to "greedy", a linear scan of the labels is performed, removing any label that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: "greedy" for ``log scales otherwise ``true`.

labelPadding

Padding in pixels between the legend and legend labels.

labelSeparation

The minimum separation that must be between label bounding boxes for them to be considered non-overlapping (default 0). This property is ignored if labelOverlap resolution is not enabled.

layout
legendX

Custom x-position for legend with orient “none”.

legendY

Custom y-position for legend with orient “none”.

offset

The offset in pixels by which to displace the legend from the data rectangle and axes.

Default value: 18.

orient

The orientation of the legend, which determines how the legend is positioned within the scene. One of "left", "right", "top", "bottom", "top-left", "top-right", "bottom-left", "bottom-right", "none".

Default value: "right"

padding

The padding between the border and content of the legend group.

Default value: 0.

rowPadding

The vertical padding in pixels between symbol legend entries.

Default value: 2.

strokeColor

Border stroke color for the full legend.

strokeDash

Border stroke dash pattern for the full legend.

strokeWidth

Border stroke width for the full legend.

symbolBaseFillColor

Default fill color for legend symbols. Only applied if there is no "fill" scale color encoding for the legend.

Default value: "transparent".

symbolBaseStrokeColor

Default stroke color for legend symbols. Only applied if there is no "fill" scale color encoding for the legend.

Default value: "gray".

symbolDirection

The default direction ("horizontal" or "vertical") for symbol legends.

Default value: "vertical".

The color of the legend symbol,

symbolLimit

The maximum number of allowed entries for a symbol legend. Additional entries will be dropped.

The symbol shape. One of the plotting shapes circle (default), square, cross, diamond, triangle-up, triangle-down, triangle-right, or triangle-left, the line symbol stroke, or one of the centered directional shapes arrow, wedge, or triangle. Alternatively, a custom SVG path string can be provided. For correct sizing, custom shape paths should be defined within a square bounding box with coordinates ranging from -1 to 1 along both the x and y dimensions.

Default value: "circle".

tickCount

The desired number of tick values for quantitative legends.

title

Set to null to disable title for the axis, legend, or header.

Text anchor position for placing legend titles.

titleBaseline

Vertical text baseline for legend titles. One of "alphabetic" (default), "top", "middle", "bottom", "line-top", or "line-bottom". The "line-top" and "line-bottom" values operate similarly to "top" and "bottom", but are calculated relative to the lineHeight rather than fontSize alone.

Default value: "top".

titleColor

The color of the legend title, can be in hex color code or regular color name.

titleFont

The font of the legend title.

titleFontSize

The font size of the legend title.

titleFontStyle

The font style of the legend title.

titleFontWeight

The font weight of the legend title. This can be either a string (e.g "bold", "normal") or a number (100, 200, 300, …, 900 where "normal" = 400 and "bold" = 700).

titleLimit

Maximum allowed pixel width of legend titles.

Default value: 180.

titleLineHeight

Line height in pixels for multi-line title text or title text with "line-top" or "line-bottom" baseline.

titleOpacity

Opacity of the legend title.

titleOrient

Orientation of the legend title.

titlePadding

The padding, in pixels, between title and legend.

Default value: 5.

unselectedOpacity

The opacity of unselected legend entries.

Default value: 0.35.

zindex

The integer z-index indicating the layering of the legend group relative to other axis, mark, and legend groups.

Methods

__init__(*args, **kwargs)

clear()

copy()

fromkeys(iterable[, value])

Create a new dictionary with keys from iterable and values set to value.

get(key[, default])

Return the value for key if key is in the dictionary, else default.

items()

keys()

pop(key[, default])

If the key is not found, return the default if given; otherwise, raise a KeyError.

popitem(/)

Remove and return a (key, value) pair as a 2-tuple.

setdefault(key[, default])

Insert key with a value of default if key is not in the dictionary.

update([E, ]**F)

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
