pliced

An experimental Chart widget for iced.

Currently there are two chart implementations, one using plotters as backend and an iced native implementation.

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();
    }
}
