pub struct ErrorBar<K, V, O: ErrorBarOrient<K, V>> { /* private fields */ }
Expand description
An error bar, which visualizes the minimum, average, and maximum of a dataset.
Unlike crate::series::Histogram
, the ErrorBar
code does not classify or aggregate data.
These operations must be done before building error bars.
Examples
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("error_bars_vertical.svg", (300, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let mut chart_builder = ChartBuilder::on(&drawing_area);
chart_builder.margin(10).set_left_and_bottom_label_area_size(20);
let mut chart_context = chart_builder.build_cartesian_2d(0.0..6.0, 0.0..6.0).unwrap();
chart_context.configure_mesh().draw().unwrap();
chart_context.draw_series(data.map(|(x, y)| {
ErrorBar::new_vertical(x, y - 0.4, y, y + 0.3, BLUE.filled(), 10)
})).unwrap();
chart_context.draw_series(data.map(|(x, y)| {
ErrorBar::new_vertical(x, y + 1.0, y + 1.9, y + 2.4, RED, 10)
})).unwrap();
This code produces two series of five error bars each, showing minima, maxima, and average values:
ErrorBar::new_vertical()
is used to create vertical error bars. Here is an example using
ErrorBar::new_horizontal()
instead:
