pliced

A chart widget integrating plotters into iced.

Note

The iced native chart widget previously included in this repository has been moved to prism.

Usage

There are two ways to use this library. You can just use the provided chart widget:

  Chart::new()
      .width(Length::Fill)
      .height(Length::Fill)
      .x_range(-1.0..3.0)
      .y_range(-1.0..5.0)
      .push_series(
          line_series(self.data.iter().copied())
              .color(iced::Color::from_rgb8(255, 0, 0).into()),
      )
      .push_series(
          line_series(self.data.iter().copied().map(|(x, y)| (x, y * 0.5)))
              .color(iced::Color::from_rgb8(0, 255, 0).into()),
      )
      .push_series(point_series(
          self.data.iter().copied().map(|(x, y)| (x + 0.5, y * 2.0)),
      ))

or define a custom chart Program which provides full access to the underlying plotters ChartBuilder:

impl pliced::Program<Message> for App {
    type State = ();

    fn draw(
        &self,
        _state: &Self::State,
        chart: &mut plotters::prelude::ChartBuilder<pliced::backend::IcedChartBackend<Renderer>>,
        _theme: &iced::Theme,
        _bounds: iced::Rectangle,
        _cursor: iced::mouse::Cursor,
    ) {
        let mut chart = chart
            .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)
            .unwrap();

        chart.configure_mesh().draw().unwrap();

        chart
            .draw_series(LineSeries::new(self.data.iter().cloned(), &RED))
            .unwrap()
            .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()
            .unwrap();
    }
}
