rgbplot
Plot colormap
Syntax
Description
Examples
Plot a Predefined Colormap
Plot the parula
colormap, and display a colorbar as a visual reference.
rgbplot(parula) hold on colormap(parula) colorbar('Ticks',[])
Plot a Custom Colormap
Create a custom colormap and plot it. Then display a colorbar as a visual reference.
r = (0:.1:.9)'; g = r.^1.8; b = r.^2.1; mymap = [r g b]; rgbplot(mymap) hold on colormap(mymap) colorbar('Ticks',[])
Input Arguments
map
— Colormap
three-column matrix of RGB triplets
Colormap to plot, specified as a three-column matrix of RGB triplets. An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of a color. The intensities must be in the range [0, 1]. For example, here is a colormap that contains five colors:
map = [0.2 0.1 0.5 0.1 0.5 0.8 0.2 0.7 0.6 0.8 0.7 0.3 0.9 1 0];
This table lists the RGB triplet values for common colors.
Color | RGB Triplet |
---|---|
yellow | [1 1 0] |
magenta | [1 0 1] |
cyan | [0 1 1] |
red | [1 0 0] |
green | [0 1 0] |
blue | [0 0 1] |
white | [1 1 1] |
black | [0 0 0] |
Alternatively, you can create the matrix by calling one of the predefined
colormap functions. Call the function as the input argument to the
rgbplot
function. For example, this command plots
the parula
colormap.
rgbplot(parula)
