init(xStart:xEnd:y:)

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

Declaration

nonisolated init<X>(xStart: PlottableValue<X>, xEnd: PlottableValue<X>, y: CGFloat? = nil) where X : Plottable

xStart:
The value plotted with x start.
xEnd:
The value plotted with x end.
y:
The y position. If y is nil, the rule will be centered vertically by default.

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

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

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