# plotContainerFrame An anchor to the frame of the chart’s plot container, or `nil` if there is no chart in the context of the chart proxy. ``` var plotContainerFrame: Anchor? { get } ``` ## Discussion The plot is the area between the x and y axes, not including the axes themselves. If the chart is scrollable, the plot container frame only includes the visible portion of the plot. Otherwise, it is the same as [`plotFrame`](/documentation/Charts/ChartProxy/plotFrame). You can convert the anchor to a frame using a `GeometryProxy`. Below is an example adding a border to the plot container: ``` Chart { ... } .chartOverlay { chartProxy in GeometryReader { geometryProxy in // Get the plot container's frame in the GeometryReader's coordinate space. // This frame stays the same when the chart scrolls. // In this example, we add a border to the plot container by stroking the frame. if let plotContainerFrame = chartProxy.plotContainerFrame { Path(geometryProxy[plotContainerFrame]) .stroke(.black, lineWidth: 1) .allowsHitTesting(false) } } } ``` --- Copyright © 2026 Apple Inc.
