Struct egui::widgets::plot::Plot

pub struct Plot { /* fields omitted */ }

A 2D plot, e.g. a graph of a function.

Plot supports multiple lines and points.

use egui::plot::{Line, Plot, Value, Values};
let sin = (0..1000).map(|i| {
    let x = i as f64 * 0.01;
    Value::new(x, x.sin())
});
let line = Line::new(Values::from_values_iter(sin));
ui.add(
    Plot::new("my_plot").line(line).view_aspect(2.0)
);

Implementations

impl Plot

pub fn new(id_source: impl Hash) -> Self

Give a unique id for each plot within the same Ui.

pub fn line(self, line: Line) -> Self

Add a data lines.

pub fn polygon(self, polygon: Polygon) -> Self

Add a polygon. The polygon has to be convex.

pub fn text(self, text: Text) -> Self

Add a text.

pub fn points(self, points: Points) -> Self

Add data points.

pub fn arrows(self, arrows: Arrows) -> Self

Add arrows.

pub fn image(self, image: PlotImage) -> Self

Add an image.

pub fn hline(self, hline: HLine) -> Self

Add a horizontal line. Can be useful e.g. to show min/max bounds or similar. Always fills the full width of the plot.

pub fn vline(self, vline: VLine) -> Self

Add a vertical line. Can be useful e.g. to show min/max bounds or similar. Always fills the full height of the plot.

pub fn data_aspect(self, data_aspect: f32) -> Self

width / height ratio of the data. For instance, it can be useful to set this to 1.0 for when the two axes show the same unit. By default the plot window’s aspect ratio is used.

pub fn view_aspect(self, view_aspect: f32) -> Self

width / height ratio of the plot region. By default no fixed aspect ratio is set (and width/height will fill the ui it is in).

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

Width of plot. By default a plot will fill the ui it is in. If you set Self::view_aspect, the width can be calculated from the height.

pub fn height(self, height: f32) -> Self

Height of plot. By default a plot will fill the ui it is in. If you set Self::view_aspect, the height can be calculated from the width.

pub fn min_size(self, min_size: Vec2) -> Self

Minimum size of the plot view.

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

Show the x-value (e.g. when hovering). Default: true.

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

Show the y-value (e.g. when hovering). Default: true.

pub fn symmetrical_x_axis(self, on: bool) -> Self

👎 Deprecated:

Renamed center_x_axis

pub fn symmetrical_y_axis(self, on: bool) -> Self

👎 Deprecated:

Renamed center_y_axis

pub fn center_x_axis(self, on: bool) -> Self

Always keep the x-axis centered. Default: false.

pub fn center_y_axis(self, on: bool) -> Self

Always keep the y-axis centered. Default: false.

pub fn allow_zoom(self, on: bool) -> Self

Whether to allow zooming in the plot. Default: true.

pub fn allow_drag(self, on: bool) -> Self

Whether to allow dragging in the plot to move the bounds. Default: true.

pub fn include_x(self, x: impl Into<f64>) -> Self

Expand bounds to include the given x value. For instance, to always show the y axis, call plot.include_x(0.0).

pub fn include_y(self, y: impl Into<f64>) -> Self

Expand bounds to include the given y value. For instance, to always show the x axis, call plot.include_y(0.0).

pub fn show_legend(self, show: bool) -> Self

👎 Deprecated:

Use Plot::legend instead

Whether to show a legend including all named items. Default: true.

pub fn legend(self, legend: Legend) -> Self

Show a legend including all named items.

Trait Implementations

impl Widget for Plot

fn ui(self, ui: &mut Ui) -> Response

Allocate space, interact, paint, and return a Response.
