  • Bone colormap

Syntax

c = bone
c = bone(m)

Description

c = bone returns the bone 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.

colormap('bone');

Figure contains an axes object. The axes object contains an object of type surface.

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

c = bone;
c = flipud(c);
colormap(c);

Figure contains an axes object. The axes object contains an object of type surface.

Open Live Script

Get a downsampled version of the bone colormap containing only twenty colors. Then display the contours of a paraboloid by applying the colormap and interpolated shading.

c = bone(20);
[X,Y] = meshgrid(-10:1:10);
Z = X.^2 + Y.^2;
surf(X,Y,Z);
colormap(c);
shading interp;
