ChartColormaps

ClassChartGuruChartGuru

public static class ChartColormaps

Evaluates ChartColormap maps from their published 256-entry tables, samples them into lookup tables and converts them to Unity gradients. Colors are sRGB, like the colors of a Gradient.

Fields

ControlPointCount

public const int ControlPointCount = 256

Number of published control points of every named map.

Returns

System.Int32

Methods

IsNamed(ChartColormap)

public static bool IsNamed(ChartColormap colormap)

Whether colormap names a published map, rather than being ChartColormap.Custom or undefined.

Parameters

Name	Type
colormap	ChartGuru.ChartColormap

Returns

System.Boolean

Evaluate(ChartColormap, float)

public static Color Evaluate(ChartColormap colormap, float t)

The color of colormap at t, from 0 at the low end to 1 at the high end, interpolated linearly between the published control points. Values outside 0 to 1 are clamped and NaN reads as 0.

Parameters

Name	Type
colormap	ChartGuru.ChartColormap
t	System.Single

Returns

UnityEngine.Color

Sample(ChartColormap, Color[])

public static void Sample(ChartColormap colormap, Color[] destination)

Fills destination with evenly spaced colors of colormap, from the low end in the first element to the high end in the last; a single element takes the middle color. Use it for lookup textures and swatches.

Parameters

Name	Type
colormap	ChartGuru.ChartColormap
destination	UnityEngine.Color[]

Sample(ChartColormap, Color32[])

public static void Sample(ChartColormap colormap, Color32[] destination)

Fills the Color32 array with evenly spaced colors from the colormap, low to high; one element receives the midpoint color.

Parameters

Name	Type
colormap	ChartGuru.ChartColormap
destination	UnityEngine.Color32[]

CreateGradient(ChartColormap)

public static Gradient CreateGradient(ChartColormap colormap)

A new opaque gradient for code that needs a Unity Gradient, which holds at most eight keys. Its keys are the eight published control points that keep it closest to the full table: within 5/255 per channel for viridis, magma, plasma and cividis, 8/255 for inferno and 12/255 for turbo. Color scales and theme colormaps evaluate the full table instead.

Parameters

Name	Type
colormap	ChartGuru.ChartColormap

Returns

UnityEngine.Gradient
