public class AreaPlot : ChartMark, IChartMark

A vectorized area plot that renders a mathematical function as a filled area. Swift Charts equivalent: AreaPlot(x: “x”, y: .linearFunction(…))

Constructors

AreaPlot(Func<float, float>, float, float)

public AreaPlot(Func<float, float> function, float domainMin = 0, float domainMax = 1)

Creates an AreaPlot with a function and domain.

Parameters

Name	Type
function	System.Func{System.Single,System.Single}
domainMin	System.Single
domainMax	System.Single

AreaPlot(Func<float, float>, Func<float, float>, float, float)

public AreaPlot(Func<float, float> upperFunction, Func<float, float> lowerFunction, float domainMin = 0, float domainMax = 1)

Creates an area between two functions.

Parameters

Name	Type
upperFunction	System.Func{System.Single,System.Single}
lowerFunction	System.Func{System.Single,System.Single}
domainMin	System.Single
domainMax	System.Single

Methods

LinearFunction(float, float, float, float)

public static AreaPlot LinearFunction(float intercept, float slope, float domainMin = 0, float domainMax = 1)

Creates a linear function area plot.

Parameters

Name	Type
intercept	System.Single
slope	System.Single
domainMin	System.Single
domainMax	System.Single

Returns

ChartGuru.AreaPlot

SineWave(float, float, float, float, float)

public static AreaPlot SineWave(float amplitude = 1, float frequency = 1, float phase = 0, float domainMin = 0, float domainMax = 6.28)

Creates a sine wave area plot.

Parameters

Name	Type
amplitude	System.Single
frequency	System.Single
phase	System.Single
domainMin	System.Single
domainMax	System.Single

Returns

ChartGuru.AreaPlot

GetSampledMarks()

public IEnumerable<AreaMark> GetSampledMarks()

Samples the function and generates AreaMark data points.

Returns

System.Collections.Generic.IEnumerable{ChartGuru.AreaMark}

Domain(float, float)

public AreaPlot Domain(float min, float max)

Sets the numeric input domain sampled by the plot; values outside the interval are not generated.

Parameters

Name	Type
min	System.Single
max	System.Single

Returns

ChartGuru.AreaPlot

Samples(int)

public AreaPlot Samples(int count)

Sets how many evenly spaced samples are generated across a function plot domain.

Parameters

Name	Type
count	System.Int32

Returns

ChartGuru.AreaPlot

InterpolationMethod(InterpolationMethod)

public AreaPlot InterpolationMethod(InterpolationMethod method)

Selects how adjacent data points are connected, affecting line and area geometry between samples.

Parameters

Name	Type
method	ChartGuru.InterpolationMethod

Returns

ChartGuru.AreaPlot

Baseline(float)

public AreaPlot Baseline(float value)

Sets the area baseline; callback overloads evaluate a separate baseline for each sampled X value.

Parameters

Name	Type
value	System.Single

Returns

ChartGuru.AreaPlot

Baseline(Func<float, float>)

public AreaPlot Baseline(Func<float, float> function)

Sets the area baseline; callback overloads evaluate a separate baseline for each sampled X value.

Parameters

Name	Type
function	System.Func{System.Single,System.Single}

Returns

ChartGuru.AreaPlot

Opacity(float)

public AreaPlot Opacity(float value)

Configures the alpha multiplier for generated marks; selector overloads evaluate it separately for each datum.

Parameters

Name	Type
value	System.Single

Returns

ChartGuru.AreaPlot

GetMorphTargets(ChartType, Rect)

public override (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 override IChartMark Clone()

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

Returns

ChartGuru.IChartMark
