ChartScrollTargetBehavior
public abstract class ChartScrollTargetBehaviorDefines how scroll positions align to data values and how paging advances through a visible chart domain.
Fields
Section titled “Fields”
public static readonly ChartScrollTargetBehavior NoneDisables snapping; scroll positions stay wherever callers set them.
Returns
ChartGuru.ChartScrollTargetBehavior
Methods
Section titled “Methods”
ValueAligned(float, float?)
Section titled “ValueAligned(float, float?)”public static ChartScrollTargetBehavior ValueAligned(float step, float? majorAlignment = null)Snaps scroll positions to the nearest multiple of step, optionally
offset by majorAlignment (so stepping aligns to a chosen value).
Parameters
| Name | Type |
|---|---|
step |
System.Single |
majorAlignment |
System.Nullable{System.Single} |
Returns
ChartGuru.ChartScrollTargetBehavior
ValueAligned(float, MajorValueAlignment, ValueAlignedLimitBehavior)
Section titled “ValueAligned(float, MajorValueAlignment, ValueAlignedLimitBehavior)”public static ChartScrollTargetBehavior ValueAligned(float step, MajorValueAlignment majorAlignment, ValueAlignedLimitBehavior limit = ValueAlignedLimitBehavior.Automatic)Snaps scroll positions using a configurable major-value alignment (unit, calendar
matching, or page-sized) and limit behavior. Swift Charts equivalent:
.valueAligned(matching:majorAlignment:limitBehavior:).
Parameters
| Name | Type |
|---|---|
step |
System.Single |
majorAlignment |
ChartGuru.MajorValueAlignment |
limit |
ChartGuru.ValueAlignedLimitBehavior |
Returns
ChartGuru.ChartScrollTargetBehavior
Categories(IEnumerable)
Section titled “Categories(IEnumerable)”public static ChartScrollTargetBehavior Categories(IEnumerable<float> values)Snaps to the nearest value in a sorted category list (useful for band axes).
Parameters
| Name | Type |
|---|---|
values |
System.Collections.Generic.IEnumerable{System.Single} |
Returns
ChartGuru.ChartScrollTargetBehavior
ValueAligned(float, float, float?, float?, ValueAlignedLimitBehavior)
Section titled “ValueAligned(float, float, float?, float?, ValueAlignedLimitBehavior)”public static ChartScrollTargetBehavior ValueAligned(float xStep, float yStep, float? xMajorAlignment = null, float? yMajorAlignment = null, ValueAlignedLimitBehavior limit = ValueAlignedLimitBehavior.Automatic)Two-axis value-aligned behavior. Snaps independently along X and Y to multiples of
the per-axis steps (with optional per-axis major alignment). Swift Charts equivalent:
.valueAligned(matchingX:majorAlignmentX:matchingY:majorAlignmentY:limitBehavior:).
Parameters
| Name | Type |
|---|---|
xStep |
System.Single |
yStep |
System.Single |
xMajorAlignment |
System.Nullable{System.Single} |
yMajorAlignment |
System.Nullable{System.Single} |
limit |
ChartGuru.ValueAlignedLimitBehavior |
Returns
ChartGuru.ChartScrollTargetBehavior
Snap(float)
Section titled “Snap(float)”public abstract float Snap(float raw)Projects raw onto the nearest valid scroll target.
Parameters
| Name | Type |
|---|---|
raw |
System.Single |
Returns
System.Single
Snap(float, in ScrollTargetContext)
Section titled “Snap(float, in ScrollTargetContext)”public virtual float Snap(float raw, in ScrollTargetContext context)Context-aware snap. Default implementation forwards to ChartGuru.ChartScrollTargetBehavior.Snap(System.Single);
behaviors that need the visible Domain (e.g. MajorValueAlignment.Page) override this.
Parameters
| Name | Type |
|---|---|
raw |
System.Single |
context |
ChartGuru.ScrollTargetContext |
Returns
System.Single

Paging
Section titled “Paging”public static ChartScrollTargetBehavior Paging { get; }Paging scroll behavior: each settle snaps the leading edge by full
ChartGuru.ScrollTargetContext.VisibleDomainLength increments. Swift Charts
equivalent: .paging.
Returns
ChartGuru.ChartScrollTargetBehavior
