To Reproduce
Using the Plotters.rs Quick Start example:
Cargo.toml
[package]
name = "plotters_bug_repr"
version = "0.1.0"
edition = "2024"
[dependencies]
plotters = { version = "0.3.7", default-features = false, features = ["svg_backend", "bitmap_backend", "bitmap_encoder", "line_series"] }src/main.rs
use plotters::prelude::*;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let root = BitMapBackend::new("0.png", (640, 480)).into_drawing_area();
root.fill(&WHITE)?;
let mut chart = ChartBuilder::on(&root)
.caption("y=x^2", ("sans-serif", 50).into_font())
.margin(5)
.x_label_area_size(30)
.y_label_area_size(30)
.build_cartesian_2d(-1f32..1f32, -0.1f32..1f32)?;
chart.configure_mesh().draw()?;
chart
.draw_series(LineSeries::new(
(-50..=50).map(|x| x as f32 / 50.0).map(|x| (x, x * x)),
&RED,
))?
.label("y = x^2")
.legend(|(x, y)| PathElement::new(vec![(x, y), (x + 20, y)], &RED));
chart
.configure_series_labels()
.background_style(&WHITE.mix(0.8))
.border_style(&BLACK)
.draw()?;
root.present()?;
Ok(())
}
With the following changes, this example compiles and runs generating a graph:
- let root = BitMapBackend::new("0.png", (640, 480)).into_drawing_area();
+ let root = SVGBackend::new("0.svg", (640, 480)).into_drawing_area();Version Information
