Constructors

ChartMark()

protected ChartMark()

ChartMark(float, float)

protected ChartMark(float x, float y)

Initializes the mark with a scalar XY point whose stable identity is derived from its coordinates.

Parameters

Name	Type
x	System.Single
y	System.Single

ChartMark(DataPoint)

protected ChartMark(DataPoint dataPoint)

Initializes the mark from an existing point, preserving range, series, identity, and category metadata.

Parameters

Name	Type
dataPoint	ChartGuru.DataPoint

Methods

GetMorphTargets(ChartType, Rect)

public abstract (Vector2 source, Vector2 target) GetMorphTargets(ChartType targetType, Rect plotArea)

Projects this mark into plot-space geometry that the morph renderer can interpolate toward the requested chart type.

Parameters

Name	Type
targetType	ChartGuru.ChartType
plotArea	UnityEngine.Rect

Returns

System.ValueTuple{UnityEngine.Vector2,UnityEngine.Vector2}

Clone()

public abstract IChartMark Clone()

Creates an independent copy of this Chart Mark; later configuration changes do not affect the original instance.

Returns

ChartGuru.IChartMark

Properties

ZIndex

public int ZIndex { get; set; }

Render order hint: marks with higher ChartGuru.ChartMark.ZIndex draw on top of marks with lower values. Renderers apply a stable sort by (SeriesIndex, ZIndex, insertion) before emit. Swift Charts equivalent: .ZIndex(Int).

Returns

System.Int32

RangedOffset

public RangedOffset? RangedOffset { get; set; }

Optional range-based offset. When set, the mark’s resolved screen position is adjusted so that its X stretches from xStart to xEnd and its Y from yStart to yEnd (in plot/domain units), instead of using the scalar ChartGuru.ChartMark.Offset. Swift Charts equivalent (iOS 17): .Offset(xStart:xEnd:yStart:yEnd:).

Returns

System.Nullable{ChartGuru.RangedOffset}

PositionAxis

public MarkAxis PositionAxis { get; set; }

The axis along which ChartGuru.ChartMark.SeriesKey-based positioning (dodging / grouping) is applied. When ChartGuru.MarkAxis.Automatic, layout derives the axis from the mark type (bars dodge along the categorical axis, etc.). Swift Charts equivalent: .Position(by: .Value(…), axis: .horizontal).

Returns

ChartGuru.MarkAxis

PositionSpan

public MarkDimension? PositionSpan { get; set; }

Per-dodge-slot dimension override. When set, layout uses this dimension for the slot width assigned to this mark inside its ChartGuru.ChartMark.PositionAxis dodge group instead of the mark’s own Width/Height. Swift Charts equivalent: .Position(by:axis:span:).

Returns

System.Nullable{ChartGuru.MarkDimension}

MarkType

public abstract ChartType MarkType { get; }

Returns

ChartGuru.ChartType

DataPoint

public virtual DataPoint DataPoint { get; set; }

Returns

ChartGuru.DataPoint

ForegroundColor

public Color ForegroundColor { get; set; }

Returns

UnityEngine.Color

Visible

public bool Visible { get; set; }

Returns

System.Boolean

SeriesKey

public object SeriesKey { get; set; }

Returns

System.Object

Accessibility

public AccessibilityInfo Accessibility { get; set; }

Per-mark accessibility metadata. Swift Charts equivalent: .accessibilityLabel, .accessibilityValue, .accessibilityHidden, .accessibilityIdentifier.

Returns

ChartGuru.AccessibilityInfo

CategoryLabel

public string CategoryLabel { get; set; }

Category label for X-axis display (e.g., “Jan”, “Feb”, “Mar”). Separate from SeriesKey/ForegroundStyleKey which determine colors and legend.

Returns

System.String

ForegroundStyleKey

public object ForegroundStyleKey { get; set; }

Key for automatic color assignment and legend generation. Swift Charts equivalent: ForegroundStyle(by:) modifier.

Returns

System.Object

ForegroundGradient

public LinearGradientStyle ForegroundGradient { get; set; }

Returns

ChartGuru.LinearGradientStyle

ForegroundGradientStyle

public GradientStyle ForegroundGradientStyle { get; set; }

General gradient style (radial, angular, elliptical, or linear via the base type). When set, takes precedence over ChartGuru.ChartMark.ForegroundGradient.

Returns

ChartGuru.GradientStyle

ShowShadow

public bool ShowShadow { get; set; }

Returns

System.Boolean

ShadowColor

public Color ShadowColor { get; set; }

Returns

UnityEngine.Color

ShadowOffset

public Vector2 ShadowOffset { get; set; }

Returns

UnityEngine.Vector2

ShadowBlur

public float ShadowBlur { get; set; }

Returns

System.Single

BlendMode

public MarkBlendMode BlendMode { get; set; }

Returns

ChartGuru.MarkBlendMode

ClipShape

public ClipShape ClipShape { get; set; }

Returns

ChartGuru.ClipShape

BlurRadius

public float BlurRadius { get; set; }

Returns

System.Single

MaskContent

public IChartContent MaskContent { get; set; }

Returns

ChartGuru.IChartContent

CompositingLayer

public bool CompositingLayer { get; set; }

Returns

System.Boolean

CustomSymbolRenderer

public Func<Rect, Color, bool> CustomSymbolRenderer { get; set; }

Custom symbol renderer callback. When set and the mark’s symbol shape is ChartGuru.SymbolShape.Custom, the renderer invokes this delegate instead of drawing a predefined shape. The callback receives the symbol’s bounding UnityEngine.Rect (in pixels) and the resolved UnityEngine.Color; it should emit geometry through the active draw sink. Return true if the symbol was drawn, false to fall back to default. Swift Charts equivalent: .Symbol() { custom View }.

Returns

System.Func{UnityEngine.Rect,UnityEngine.Color,System.Boolean}

Annotation

public AnnotationConfig Annotation { get; }

Returns

ChartGuru.AnnotationConfig

Opacity

public float Opacity { get; set; }

Returns

System.Single

Offset

public Vector2 Offset { get; }

Offset applied to the mark in plot coordinates. Swift Charts equivalent: .Offset(x:y:)

Returns

UnityEngine.Vector2
