# ChartScrollTargetBehavior A type that configures the scroll behavior of charts. ``` protocol ChartScrollTargetBehavior : ScrollTargetBehavior ``` ## Topics ### Supporting types [`struct MajorValueAlignment`](/documentation/Charts/MajorValueAlignment) A type that defines how the valigned aligned chart scroll target behavior aligns to major values on swipe. [`struct ValueAlignedLimitBehavior`](/documentation/Charts/ValueAlignedLimitBehavior) A type that defines the amount of marks that can be scrolled at a time. [`struct ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ValueAlignedChartScrollTargetBehavior) A scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes. ### Instance Methods [`func updateTarget(inout ScrollTarget, context: ChartScrollTargetBehaviorContext)`](/documentation/Charts/ChartScrollTargetBehavior/updateTarget(_:context:)) ### Type Methods [`static func valueAligned(matching: DateComponents, majorAlignment: MajorValueAlignment?, limitBehavior: ValueAlignedLimitBehavior) -> ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ChartScrollTargetBehavior/valueAligned(matching:majorAlignment:limitBehavior:)) Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes. [`static func valueAligned

(unit: P, majorAlignment: MajorValueAlignment

?, limitBehavior: ValueAlignedLimitBehavior) -> ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ChartScrollTargetBehavior/valueAligned(unit:majorAlignment:limitBehavior:)) Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes. [`static func valueAligned(xMatching: DateComponents, yMatching: DateComponents, xMajorAlignment: MajorValueAlignment?, yMajorAlignment: MajorValueAlignment?, limitBehavior: ValueAlignedLimitBehavior) -> ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ChartScrollTargetBehavior/valueAligned(xMatching:yMatching:xMajorAlignment:yMajorAlignment:limitBehavior:)) Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes. [`static func valueAligned(xMatching: DateComponents, yUnit: Y, xMajorAlignment: MajorValueAlignment?, yMajorAlignment: MajorValueAlignment?, limitBehavior: ValueAlignedLimitBehavior) -> ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ChartScrollTargetBehavior/valueAligned(xMatching:yUnit:xMajorAlignment:yMajorAlignment:limitBehavior:)) Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes. [`static func valueAligned(xUnit: X, yMatching: DateComponents, xMajorAlignment: MajorValueAlignment?, yMajorAlignment: MajorValueAlignment?, limitBehavior: ValueAlignedLimitBehavior) -> ValueAlignedChartScrollTargetBehavior`](/documentation/Charts/ChartScrollTargetBehavior/valueAligned(xUnit:yMatching:xMajorAlignment:yMajorAlignment:limitBehavior:)) Creates a scroll target behavior that aligns to values spaced at regular intervals along the scrollable axes.
