Struct plotters::chart::ChartContext

pub struct ChartContext<'a, DB: DrawingBackend, CT: CoordTranslate> { /* fields omitted */ }

The context of the chart. This is the core object of Plotters. Any plot/chart is abstracted as this type, and any data series can be placed to the chart context.

Methods

impl<'a, DB: DrawingBackend, XT: Debug, YT: Debug, X: Ranged<ValueType = XT>, Y: Ranged<ValueType = YT>> ChartContext<'a, DB, RangedCoord<X, Y>>

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

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

impl<'a, DB: DrawingBackend + 'a, CT: CoordTranslate> ChartContext<'a, DB, CT>

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

Configure the styles for drawing series labels in the chart

pub fn plotting_area(&self) -> &DrawingArea<DB, CT>

Get a reference of underlying plotting area

impl<'a, DB: DrawingBackend, CT: ReverseCoordTranslate> ChartContext<'a, DB, CT>

pub fn into_coord_trans(self) -> impl Fn(BackendCoord) -> Option<CT::From>

Convert the chart context into an closure that can be used for coordinate translation

impl<'a, DB: DrawingBackend, X: Ranged, Y: Ranged> ChartContext<'a, DB, RangedCoord<X, Y>>

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 draw_series<E, R, S>(
    &mut self,
    series: S
) -> Result<&mut SeriesAnno<'a, DB>, DrawingAreaErrorKind<DB::ErrorType>> where
    &'b E: PointCollection<'b, (X::ValueType, Y::ValueType)>,
    E: Drawable<DB>,
    R: Borrow<E>,
    S: IntoIterator<Item = R>, 

Draw a data series. A data series in Plotters is abstracted as an iterator of elements
