Struct plotters::chart::DualCoordChartContext

pub struct DualCoordChartContext<'a, DB: DrawingBackend, CT1: CoordTranslate, CT2: CoordTranslate> { /* private fields */ }

The chart context that has two coordinate system attached. This situation is quite common, for example, we with two different coodinate system. For instance this example This is done by attaching a second coordinate system to ChartContext by method ChartContext::set_secondary_coord. For instance of dual coordinate charts, see this example. Note: DualCoordChartContext is always deref to the chart context.

• If you want to configure the secondary axis, method DualCoordChartContext::configure_secondary_axes
• If you want to draw a series using secondary coordinate system, use DualCoordChartContext::draw_secondary_series. And method ChartContext::draw_series will always use primary coordinate spec.

Methods from Deref<Target = ChartContext<'a, DB, CT1>>

pub fn configure_mesh(&mut self) -> MeshStyle<'a, '_, X, Y, DB>

Initialize a mesh configuration object and mesh drawing can be finalized by calling the function MeshStyle::draw.

pub fn x_range(&self) -> Range<X::ValueType>

Get the range of X axis

pub fn y_range(&self) -> Range<Y::ValueType>

Get range of the Y axis

pub fn backend_coord( &self, coord: &(X::ValueType, Y::ValueType) ) -> BackendCoord

Maps the coordinate to the backend coordinate. This is typically used with an interactive chart.

pub fn configure_axes(&mut self) -> Axes3dStyle<'a, '_, X, Y, Z, DB>

Create an axis configuration object, to set line styles, labels, sizes, etc.

Default values for axis configuration are set by function Axes3dStyle::new().

Example

use plotters::prelude::*;
let drawing_area = SVGBackend::new("configure_axes.svg", (300, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let mut chart_builder = ChartBuilder::on(&drawing_area);
let mut chart_context = chart_builder.margin_bottom(30).build_cartesian_3d(0.0..4.0, 0.0..3.0, 0.0..2.7).unwrap();
chart_context.configure_axes().tick_size(8).x_labels(4).y_labels(3).z_labels(2)
    .max_light_lines(5).axis_panel_style(GREEN.mix(0.1)).bold_grid_style(BLUE.mix(0.3))
    .light_grid_style(BLUE.mix(0.2)).label_style(("Calibri", 10))
    .x_formatter(&|x| format!("x={x}")).draw().unwrap();

The resulting chart reflects the customizations specified through configure_axes():

All these customizations are Axes3dStyle methods.

In the chart, tick_size(8) produces tick marks 8 pixels long. You can use (5u32).percent().max(5).in_pixels(chart.plotting_area() to tell Plotters to calculate the tick mark size as a percentage of the dimensions of the figure. See crate::style::RelativeSize and crate::style::SizeDesc for more information.

x_labels(4) specifies a maximum of 4 tick marks and labels in the X axis. max_light_lines(5) specifies a maximum of 5 minor grid lines between any two tick marks. axis_panel_style(GREEN.mix(0.1)) specifies the style of the panels in the background, a light green color. bold_grid_style(BLUE.mix(0.3)) and light_grid_style(BLUE.mix(0.2)) specify the style of the major and minor grid lines, respectively. label_style() specifies the text style of the axis labels, and x_formatter(|x| format!("x={x}")) specifies the string format of the X axis labels.

ChartContext::configure_mesh(), a similar function for 2D plots

pub fn with_projection<P: FnOnce(ProjectionMatrixBuilder) -> ProjectionMatrix>( &mut self, pf: P ) -> &mut Self

Override the 3D projection matrix. This function allows to override the default projection matrix.

• pf: A function that takes the default projection matrix configuration and returns the projection matrix. This function will allow you to adjust the pitch, yaw angle and the centeral point of the projection, etc. You can also build a projection matrix which is not relies on the default configuration as well.

pub fn set_3d_pixel_range(&mut self, size: (i32, i32, i32)) -> &mut Self

Sets the 3d coordinate pixel range.

pub fn configure_series_labels<'b>( &'b mut self ) -> SeriesLabelStyle<'a, 'b, DB, CT>where DB: 'a,

Configure the styles for drawing series labels in the chart

Example

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("configure_series_labels.svg", (300, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
let mut chart_builder = ChartBuilder::on(&drawing_area);
chart_builder.margin(7).set_left_and_bottom_label_area_size(20);
let mut chart_context = chart_builder.build_cartesian_2d(0.0..5.5, 0.0..5.5).unwrap();
chart_context.configure_mesh().draw().unwrap();
chart_context.draw_series(LineSeries::new(data, BLACK)).unwrap().label("Series 1")
    .legend(|(x,y)| Rectangle::new([(x - 15, y + 1), (x, y)], BLACK));
chart_context.configure_series_labels().position(SeriesLabelPosition::UpperRight).margin(20)
    .legend_area_size(5).border_style(BLUE).background_style(BLUE.mix(0.1)).label_font(("Calibri", 20)).draw().unwrap();

The result is a chart with one data series labeled “Series 1” in a blue legend box:
