Struct Line 

pub struct Line<'a> { /* private fields */ }

A series of values forming a path.

Implementations

impl<'a> Line<'a>

pub fn new(name: impl Into<String>, series: impl Into<PlotPoints<'a>>) -> Self

pub fn stroke(self, stroke: impl Into<Stroke>) -> Self

Add a stroke.

pub fn gradient_color( self, callback: Arc<dyn Fn(PlotPoint) -> Color32 + Send + Sync>, gradient_fill: bool, ) -> Self

Add an optional gradient color to the stroke using a callback. The callback receives a PlotPoint as input with the current X and Y values and should return a Color32 to be used as the stroke color for that point.

Setting the gradient_fill parameter to true will use the gradient color callback for the fill area as well when fill() is set.

pub fn width(self, width: impl Into<f32>) -> Self

Stroke width. A high value means the plot thickens.

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

Stroke color. Default is Color32::TRANSPARENT which means a color will be auto-assigned.

pub fn fill(self, y_reference: impl Into<f32>) -> Self

Fill the area between this line and a given horizontal reference line.

pub fn fill_alpha(self, alpha: impl Into<f32>) -> Self

Set the fill area’s alpha channel. Default is 0.05.

pub fn style(self, style: LineStyle) -> Self

Set the line’s style. Default is LineStyle::Solid.

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
