init(xStart:xEnd:y:)

Creates a horizontal rule mark that plots values on its x interval and on y.

Declaration

nonisolated init<X, Y>(xStart: PlottableValue<X>, xEnd: PlottableValue<X>, y: PlottableValue<Y>) where X : Plottable, Y : Plottable

Parameters

xStart:
The value plotted with x start.
xEnd:
The value plotted with x end.
y:
The value plotted with y.

Discussion

Use this initializer to create a horizontal rule at x positions from xStart to xEnd to a y position:

Chart(data) {
    RuleMark(
        xStart: .value("Start Date", $0.startDate),
        xEnd: .value("End Date", $0.endDate),
        y: .value("Pollen Source", $0.source)
    )
}

See the second code example in RuleMark for the setup of the structure that contains the startDate, endDate, and source properties.
