# init(x:y:) Creates a point mark that plots values to x and y. ``` nonisolated init(x: PlottableValue, y: PlottableValue) where X : Plottable, Y : Plottable ``` ## Parameters `x` The value plotted with x. `y` The value plotted with y. ## Discussion ### Discussion Use this initializer to plot one property with x and another property with y: ```swift Chart(data) { PointMark( x: .value("Wing Length", $0.wingLength), y: .value("Wing Length", $0.wingWidth) ) } ```  For more background, see the first example used in [`PointMark`](/documentation/Charts/PointMark) which shows the structure that contains the `wingLength` and `wingHeight` properties. --- Copyright © 2026 Apple Inc.
