Interface EChartsComponentGroup

Where a component's view drew itself, in the chart's own pixels.

A zrender group: its bounding rect is in the group's local coordinates, and the transform, [a, b, c, d, e, f], carries them into the chart's.

interface EChartsComponentGroup {
    getBoundingRect: () => {
        x: number;
        y: number;
        width: number;
        height: number;
    };
    getComputedTransform?: () => number[] | null | undefined;
    x?: number;
    y?: number;
}
