Struct BarChart 

pub struct BarChart { /* private fields */ }

A bar chart.

Implementations

impl BarChart

pub fn new(name: impl Into<String>, bars: Vec<Bar>) -> Self

Create a bar chart. It defaults to vertically oriented elements.

pub fn color(self, color: impl Into<Color32>) -> Self

Set the default color. It is set on all elements that do not already have a specific color. This is the color that shows up in the legend. It can be overridden at the bar level (see [Bar]). Default is Color32::TRANSPARENT which means a color will be auto-assigned.

pub fn vertical(self) -> Self

Set all elements to be in a vertical orientation. Argument axis will be X and bar values will be on the Y axis.

pub fn horizontal(self) -> Self

Set all elements to be in a horizontal orientation. Argument axis will be Y and bar values will be on the X axis.

pub fn width(self, width: f64) -> Self

Set the width (thickness) of all its elements.

pub fn element_formatter( self, formatter: Box<dyn Fn(&Bar, &Self) -> String>, ) -> Self

Add a custom way to format an element. Can be used to display a set number of decimals or custom labels.

pub fn stack_on(self, others: &[&Self]) -> Self

Stacks the bars on top of another chart. Positive values are stacked on top of other positive values. Negative values are stacked below other negative values.

pub fn name(self, name: impl ToString) -> Self

Name of this plot item.

This name will show up in the plot legend, if legends are turned on.

Setting the name via this method does not change the item’s id, so you can use it to change the name dynamically between frames without losing the item’s state. You should make sure the name passed to Self::new is unique and stable for each item, or set unique and stable ids explicitly via Self::id.

pub fn highlight(self, highlight: bool) -> Self

Highlight this plot item, typically by scaling it up.

If false, the item may still be highlighted via user interaction.

pub fn allow_hover(self, hovering: bool) -> Self

Allowed hovering this item in the plot. Default: true.

pub fn id(self, id: impl Into<Id>) -> Self

Sets the id of this plot item.

By default the id is determined from the name passed to Self::new, but it can be explicitly set to a different value.

Trait Implementations
