init(x:yStart:yEnd:)

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

Declaration

nonisolated init<Y>(x: CGFloat? = nil, yStart: PlottableValue<Y>, yEnd: PlottableValue<Y>) where Y : Plottable

x:
The x position. If x is nil, the rule will be centered horizontally by default.
yStart:
The value plotted with y start.
yEnd:
The value plotted with y end.

Use this initializer to create a vertical rule at y positions from yStart to yEnd for a single x position:

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