init(xStart:xEnd:y:)

Creates an area mark that plots values with a horizontal interval.

Declaration

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

Parameters

  • xStart:

    The starting horizontal position for the mark.

  • xEnd:

    The ending horizontal position for the mark.

  • y:

    The vertical position for the mark.

Discussion

Use this initializer to create a range area chart with horizontal intervals. For example you can create a region that encompasses all the temperatures over the course of a day, across a number of days:

Chart(data) { day in
    AreaMark(
        xStart: .value("Minimum Temperature", minimumTemperature),
        xEnd: .value("Maximum Temperature", day.maximumTemperature),
        y: .value("Date", day.date)
    )
}

If you want to plot values that have a vertical interval, use init(x:yStart:yEnd:) instead.
