winter

Winter colormap array

• 

Syntax

c = winter

c = winter(m)

Description

c = winter returns the winter colormap as a three-column array with the same number of rows as the colormap for the current figure (gcf). If no figure exists, then the number of rows is equal to the default length of 256. Each row in the array contains the red, green, and blue intensities for a specific color. The intensities are in the range [0,1], and the color scheme looks like this image.

c = winter(m) returns the colormap with m colors.

Examples

Reverse the Colormap

Plot a surface and assign the winter colormap.

surf(peaks);
colormap('winter');

Get the winter colormap array and reverse the order. Then apply the modified colormap to the surface.

c = winter;
c = flipud(c);
colormap(c);

Downsample the Winter Colormap

Get a downsampled version of the winter colormap containing only ten colors. Then display the contours of the peaks function by applying the colormap and interpolated shading.

c = winter(10);
surf(peaks);
colormap(c);
shading interp;

Input Arguments

m — Number of colors

256 (default) | nonnegative integer

Number of colors, specified as a nonnegative integer. The default value of m is the number of colors in the current figure's colormap. If no figure exists, the default value is 256.

Data Types: single | double

Version History

Introduced before R2006a

R2019b: Colormaps have 256 colors by default

Starting in R2019b, colormaps have 256 colors by default.

In R2019a and previous releases, the default size is 64. If you have code that depends on a colormap having 64 colors, specify the number of colors when you set the colormap for the figure, axes, or chart. For example, colormap(winter(64)) sets the figure's colormap to the 64-color winter colormap.

Alternatively, you can change the default colormap for all figures within your MATLAB^® session:

set(groot,'defaultFigureColormap',winter(64))
