Implementations

impl ChartTooltip

pub fn new() -> ChartTooltip

A tooltip with the category on top and a square before each series.

pub fn indicator(self, indicator: ChartIndicator) -> ChartTooltip

How each row shows its color.

pub fn hide_label(self) -> ChartTooltip

Leaves out the category on top.

pub fn label(self, label: impl Into<String>) -> ChartTooltip

Writes this on top, in place of the category.

pub fn label_format( self, format: impl Fn(&str) -> String + 'static, ) -> ChartTooltip

Writes the category on top in another way, such as a date in full.

pub fn value_format( self, format: impl Fn(f64) -> String + 'static, ) -> ChartTooltip

Writes values in another way than on the axis, such as with their unit.

pub fn show_total(self, name: impl Into<String>) -> ChartTooltip

Adds a last row with the sum of the series, under this name.

pub fn icons(self) -> ChartTooltip

Shows the icons of the series in place of their colors.

pub fn show_percent(self) -> ChartTooltip

Writes after each value its share: of the circle in a pie or a doughnut, of the category in the others.

pub fn value_color( self, color: impl Fn(usize, f64) -> Option<Semantic> + 'static, ) -> ChartTooltip

Colors a value by what it says, such as a loss in red. It is given the index of the series and the value; None leaves it in the color of the text.

pub fn no_indicator_for(self, series: impl Into<String>) -> ChartTooltip

The row of this series has no square or bar, for a value that is not one of those the chart tells apart, such as a target.

pub fn content( self, content: impl Fn(usize, &str) -> Box<dyn View> + 'static, ) -> ChartTooltip

Writes the panel with a view of your own, given the index and the name of the category. A screen reader still hears the values.

pub fn no_cursor(self) -> ChartTooltip

Leaves out the strip or line that marks the category on the chart.
