Legend schema wrapper.

Properties of a legend or boolean flag for determining whether to show it.

Parameters:

ariabool, dict, ExprRef

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

columnPaddingdict, float, ExprRef

The horizontal padding in pixels between symbol legend entries.

Default value: 10.

cornerRadiusdict, float, ExprRef

Corner radius for the full legend.

descriptionstr, dict, ExprRef

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.
