Interface LinePiece

One piece of a piecewise series color (ECharts visualMap pieces): values in the interval take color. Bounds are optional (open ends); gte wins over gt and lte over lt when both are given (ECharts).

interface LinePiece {
    color: ColorInput;
    gt?: number;
    gte?: number;
    lt?: number;
    lte?: number;
}
