valueAligned(unit:majorAlignment:limitBehavior:)

Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes.

Declaration

static func valueAligned<P>(unit: P, majorAlignment: MajorValueAlignment<P>? = nil, limitBehavior: ValueAlignedLimitBehavior = .automatic) -> ValueAlignedChartScrollTargetBehavior where Self == ValueAlignedChartScrollTargetBehavior, P : Plottable, P : Numeric

Parameters

unit:
The alignment unit. When the user finishes a scroll gesture, the chart will snap to align to the given unit or the end of the domain.
majorAlignment:
The behavior for aligning to major values. When the user swipes on the chart, the chart will snap to the next or previous major unit depending on the swipe direction. When enabled, the default major unit is a page.
limitBehavior:
The scroll limit behavior.

Discussion

Use this method to create a scroll behavior that aligns to desired units.

Chart(data) {
    BarMark(
        x: .value("x", $0.x),
        y: .value("y", $0.y)
    )
}
.chartScrollableAxes(.horizontal)
.chartScrollTargetBehavior(.valueAligned(unit: 10))

The value aligned behavior can be set to align to major units on swipes. When enabled, the default major unit is a page and the behavior on swipe is similar to the .paged behavior.
