Struct plotters::element::EmptyElement
source · pub struct EmptyElement<Coord, DB: DrawingBackend> { /* private fields */ }
Expand description
An empty composable element. This is the starting point of a composed element.
Example
use plotters::prelude::*;
let data = [(1.0, 3.3), (2., 2.1), (3., 1.5), (4., 1.9), (5., 1.0)];
let drawing_area = SVGBackend::new("composable.svg", (300, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let mut chart_builder = ChartBuilder::on(&drawing_area);
chart_builder.margin(7).set_left_and_bottom_label_area_size(20);
let mut chart_context = chart_builder.build_cartesian_2d(0.0..5.5, 0.0..5.5).unwrap();
chart_context.configure_mesh().draw().unwrap();
chart_context.draw_series(data.map(|(x, y)| {
EmptyElement::at((x, y)) // Use the guest coordinate system with EmptyElement
+ Circle::new((0, 0), 10, BLUE) // Use backend coordinates with the rest
+ Cross::new((4, 4), 3, RED)
+ Pixel::new((4, -4), RED)
+ TriangleMarker::new((-4, -4), 4, RED)
})).unwrap();
The result is a data series where each point consists of a circle, a cross, a pixel, and a triangle:
