init(x:yStart:yEnd:)

Creates a vertical rule mark with an x encoding and y interval encoding.

Declaration

nonisolated init<X, Y>(x: PlottableValue<X>, yStart: PlottableValue<Y>, yEnd: PlottableValue<Y>) where X : Plottable, Y : Plottable

Parameters

x:
The value plotted with x.
yStart:
The value plotted with y start.
yEnd:
The value plotted with y end.

Discussion

Use this initializer to create a vertical line at y positions from yStart to yEnd to an x position:

Chart(data) {
    RuleMark(
        x: .value("Pollen Source", $0.source),
        yStart: .value("Start Date", $0.startDate),
        yEnd: .value("End Date", $0.endDate)
    )
}
