Struct audio_processor_testing_helpers::charts::ChartBuilder

source · 
pub struct ChartBuilder<'a, 'b, DB>
where
    DB: DrawingBackend,
{ /* private fields */ }
Expand description

The helper object to create a chart context, which is used for the high-level figure drawing.

With the help of this object, we can convert a basic drawing area into a chart context, which allows the high-level charting API being used on the drawing area.

See ChartBuilder::on() for more information and examples.

Implementations§

source§

impl<'a, 'b, DB> ChartBuilder<'a, 'b, DB>
where DB: DrawingBackend,

source

pub fn on(root: &'a DrawingArea<DB, Shift>) -> ChartBuilder<'a, 'b, DB>

Create a chart builder on the given drawing area

  • root: The root drawing area
  • Returns: The chart builder object
Example
use plotters::prelude::*;
let drawing_area = SVGBackend::new("chart_builder_on.svg", (300, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let mut chart_builder = ChartBuilder::on(&drawing_area);
chart_builder.margin(5).set_left_and_bottom_label_area_size(35)
.caption("Figure title or caption", ("Calibri", 20, FontStyle::Italic, &RED).into_text_style(&drawing_area));
let mut chart_context = chart_builder.build_cartesian_2d(0.0..3.8, 0.0..2.8).unwrap();
chart_context.configure_mesh().draw().unwrap();

The result is a chart with customized margins, label area sizes, and title:
