Struct GeoLayout 

pub struct GeoLayout {
    pub name: String,
    pub regions: Vec<GeoRegionLayout>,
    pub transform: Transform2D,
}

A map, in pixel space.

Fields

name: String

The name of the map.

regions: Vec<GeoRegionLayout>

The regions of the map, projected into the chart.

transform: Transform2D

The transform that takes a longitude and a latitude to a point of the chart.

Implementations

impl GeoLayout

Inherent implementation of GeoLayout.

pub fn compute(data: &MapData, rect: BBox, aspect_scale: f64) -> Self

Projects a map into a rectangle of the chart.

The projection is the one ECharts uses: the longitude and the latitude are scaled evenly, and the height of the map is shortened by the aspect scale so that a map of the mid-latitudes does not look stretched sideways. The map is centred in the rectangle and takes most of it.

Arguments

• &MapData - Shared reference to a MapData.
• BBox - A BBox parameter.
• f64 - A 64-bit float (f64).

pub fn region(&self, name: &str) -> Option<&GeoRegionLayout>

Returns the region with the given name.

Arguments

• &str - Shared reference to a str.

Returns

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