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

Fields

aria: Option<Aria>

clip_height: Option<CornerRadiusUnion>

column_padding: Option<CornerRadiusUnion>

columns: Option<CornerRadiusUnion>

corner_radius: Option<CornerRadiusUnion>

description: Option<Color>

direction: Option<Orientation>

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

Default value: - For top-/bottom-oriented legends, "horizontal" - For left-/right-oriented legends, "vertical" - For top/bottom-left/right-oriented legends, "horizontal" for gradient legends and "vertical" for symbol legends.

fill_color: Option<Color>

format: Option<Format>

When used with the default "number" and "time" format type, the text formatting pattern for labels of guides (axes, legends, headers) and text marks.

• If the format type is "number" (e.g., for quantitative fields), this is D3's number format pattern. - If the format type is "time" (e.g., for temporal fields), this is D3's time format pattern.

See the format documentation for more examples.

When used with a custom formatType, this value will be passed as format alongside datum.value to the registered function.

Default value: Derived from numberFormat config for number format and from timeFormat config for time format.

format_type: Option<String>

The format type for labels. One of "number", "time", or a registered custom format type.

Default value: - "time" for temporal fields and ordinal and nominal fields with timeUnit. - "number" for quantitative fields as well as ordinal and nominal fields without timeUnit.

gradient_length: Option<FontSize>

gradient_opacity: Option<CornerRadiusUnion>

gradient_stroke_color: Option<Color>

gradient_stroke_width: Option<FontSize>

gradient_thickness: Option<FontSize>

grid_align: Option<GridAlign>

label_align: Option<TitleAlignUnion>

label_baseline: Option<TextBaseline>

label_color: Option<Color>

label_expr: Option<String>

Vega expression for customizing labels.

Note: The label text and value can be assessed via the label and value properties of the legend's backing datum object.

label_font: Option<Color>

label_font_size: Option<FontSize>

label_font_style: Option<Color>

label_font_weight: Option<FontWeightUnion>

label_limit: Option<CornerRadiusUnion>

label_offset: Option<CornerRadiusUnion>

label_opacity: Option<CornerRadiusUnion>

label_overlap: Option<LabelOverlapUnion>

label_padding: Option<CornerRadiusUnion>

label_separation: Option<CornerRadiusUnion>

legend_x: Option<CornerRadiusUnion>

legend_y: Option<CornerRadiusUnion>

offset: Option<CornerRadiusUnion>

orient: Option<LegendOrient>

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: Option<CornerRadiusUnion>

row_padding: Option<CornerRadiusUnion>

stroke_color: Option<Color>

symbol_dash: Option<StrokeDashUnion>

symbol_dash_offset: Option<CornerRadiusUnion>

symbol_fill_color: Option<Color>

symbol_limit: Option<CornerRadiusUnion>

symbol_offset: Option<CornerRadiusUnion>

symbol_opacity: Option<CornerRadiusUnion>

symbol_size: Option<FontSize>

symbol_stroke_color: Option<Color>

symbol_stroke_width: Option<FontSize>

symbol_type: Option<Color>

tick_count: Option<TickCount>

tick_min_step: Option<CornerRadiusUnion>

The minimum desired step between legend ticks, in terms of scale domain values. For example, a value of 1 indicates that ticks should not be less than 1 unit apart. If tickMinStep is specified, the tickCount value will be adjusted, if necessary, to enforce the minimum step value.

Default value: undefined

title: RemovableValue<LegendText>

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 part of the title (e.g., "Sum of Profit"). If the field is binned or has a time unit applied, the applied function is shown in parentheses (e.g., "Profit (binned)", "Transaction Date (year-month)"). Otherwise, the title is simply the field name.

Notes:

1. 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.

2. If both field definition's title and axis, header, or legend title are defined, axis/header/legend title will be used.

title_align: Option<TitleAlignUnion>

title_anchor: Option<TitleAnchorUnion>

title_baseline: Option<TextBaseline>

title_color: Option<Color>

title_font: Option<Color>

title_font_size: Option<CornerRadiusUnion>

title_font_style: Option<Color>

title_font_weight: Option<FontWeightUnion>

title_limit: Option<FontSize>

title_line_height: Option<CornerRadiusUnion>

title_opacity: Option<CornerRadiusUnion>

title_orient: Option<TitleOrientUnion>

title_padding: Option<CornerRadiusUnion>

legend_type: Option<LegendType>

The type of the legend. Use "symbol" to create a discrete legend and "gradient" for a continuous color gradient.

Default value: "gradient" for non-binned quantitative fields and temporal fields; "symbol" otherwise.

values: Option<Values>

Explicitly set the visible legend values.

zindex: Option<f64>

A non-negative integer indicating the z-index of the legend. If zindex is 0, legend should be drawn behind all chart elements. To put them in front, use zindex = 1.
