(length: P) -> some View where P : Plottable, P : Numeric ``` ## Parameters `length` The length of the visible domain measured in data units. For categorical data, this should be the number of visible categories. ## Discussion Use this method to control how much of the chart is visible in a scrollable chart. The example below sets the visible portion of the chart to 10 units in the X axis. ``` Chart(data) { BarMark( x: .value("x", $0.x), y: .value("y", $0.y) ) } .chartScrollableAxes(.horizontal) .chartXVisibleDomain(length: 10) ``` --- Copyright © 2026 Apple Inc.
