Implementations

impl LegendBuilder

pub fn aria<VALUE: Into<Aria>>(&mut self, value: VALUE) -> &mut Self

pub fn columns<VALUE: Into<CornerRadiusUnion>>( &mut self, value: VALUE ) -> &mut Self

pub fn corner_radius<VALUE: Into<CornerRadiusUnion>>( &mut self, value: VALUE ) -> &mut Self

pub fn description<VALUE: Into<Box<Color>>>( &mut self, value: VALUE ) -> &mut Self

pub fn direction<VALUE: Into<Orientation>>(&mut self, value: VALUE) -> &mut Self

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.

pub fn fill_color<VALUE: Into<Box<Color>>>(&mut self, value: VALUE) -> &mut Self

pub fn format<VALUE: Into<Format>>(&mut self, value: VALUE) -> &mut Self

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.

pub fn format_type<VALUE: Into<String>>(&mut self, value: VALUE) -> &mut Self

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.

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"

pub fn tick_count<VALUE: Into<TickCount>>(&mut self, value: VALUE) -> &mut Self

pub fn tick_min_step<VALUE: Into<CornerRadiusUnion>>( &mut self, value: VALUE ) -> &mut Self

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

pub fn title<VALUE: Into<RemovableValue<LegendText>>>( &mut self, value: VALUE ) -> &mut Self

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.

pub fn legend_type<VALUE: Into<LegendType>>( &mut self, value: VALUE ) -> &mut Self

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.

pub fn values<VALUE: Into<Values>>(&mut self, value: VALUE) -> &mut Self

Explicitly set the visible legend values.

pub fn zindex<VALUE: Into<f64>>(&mut self, value: VALUE) -> &mut Self

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.

pub fn build(&self) -> Result<Legend, LegendBuilderError>

Builds a new Legend.

Errors
