Struct ChartLayout 

pub struct ChartLayout {
    pub width: f64,
    pub height: f64,
    pub grids: Vec<GridLayout>,
    pub series: Vec<SeriesLayout>,
    pub geo: Vec<GeoLayout>,

The whole layout of a chart.

Fields

width: f64

The width of the chart, in canvas pixels.

height: f64

The height of the chart, in canvas pixels.

grids: Vec<GridLayout>

The grids of the chart.

series: Vec<SeriesLayout>

The series of the chart.

geo: Vec<GeoLayout>

The maps of the chart, projected into the plot area.

title_rect: Option<BBox>

The rectangle the title occupies.

legend_rect: Option<BBox>

The rectangle the legend occupies.

plot_rect: BBox

The rectangle the chart’s plot area occupies.

Implementations

impl ChartLayout

Inherent implementation of ChartLayout.

pub fn compute( option: &ChartOption, width: f64, height: f64, measurer: &TextMeasurer, ) -> ChartLayout

Computes the layout of a chart.

The layout is the bridge between the option and the display list: it resolves the sizes, computes the scales and the ticks, and places every data point in pixel space. The renderer then only has to turn the result into drawing instructions.

measurer is used to size the axis labels; passing a measurer that has already measured the same labels costs nothing, because the measurements are cached.

Arguments

• &ChartOption - Shared reference to a ChartOption.
• f64 - A 64-bit float (f64).
• &TextMeasurer - Shared reference to a TextMeasurer.

Returns

• ChartLayout - A ChartLayout value.

pub fn compute_with_maps( option: &ChartOption, width: f64, height: f64, measurer: &TextMeasurer, maps: &MapRegistry, ) -> ChartLayout

Computes the layout of a chart that draws maps.

The geometry of a map is far too large to live in an option: the same map is drawn by every chart of an application, and it is registered once. The registry is where the charts look it up.

Arguments

• &ChartOption - Shared reference to a ChartOption.
• f64 - A 64-bit float (f64).
• &TextMeasurer - Shared reference to a TextMeasurer.
• &MapRegistry - Shared reference to a MapRegistry.

Returns

• ChartLayout - A ChartLayout value.

pub fn geo(&self, name: &str) -> Option<&GeoLayout>

Returns the map with the given name.

A chart can hold more than one map: a geo component and a map series may draw different maps, and two map series may draw the same one twice.

Arguments

• &str - Shared reference to a str.

Returns

• Option<&GeoLayout> - Some(...) on success, None otherwise.
