SETCOLORMAP

Purpose:

Sets the colormap for density and shaded plots.

Syntax:

SETCOLORMAP(map)

map

An Nx3 array of RGB (red, green blue) triples.

Returns:

Nothing.

Example:

all = (0..255)/255

zip = zeros(256, 1);

map1 = ravel(all, all, all);

map2 = ravel(all, zip, all);

map3 = ravel(all, all, zip);

map4 = ravel(zip, all, all);

W1: setcolormap(map1);showcmap();

W2: setcolormap(map2);showcmap();

W3: setcolormap(map3);showcmap();

W4: setcolormap(map4);showcmap();

$image\setcmap.png$

W1 creates and displays a black to white colormap.

W2 creates and displays a black to magenta colormap.

W3 creates and displays a black to yellow colormap.

W4 creates and displays a black to cyan colormap.

Example:

W1: setshading("black", "white");showcmap()

W2: setshading("black", "magenta");showcmap()

W3: setshading("black", "yellow");showcmap()

W4: setshading("black", "lcyan");showcmap()

Same as above, except the colormaps are generated directly by SETSHADING using color names.

Remarks:

The colormap must be an array of N rows by 3 columns where 1 <= N <= 255. Each individual RGB (red, green, blue) value is a real number ranging from 0 to 1.0.

See DEFCOLOR to define a single color.

See SETSHADING to create colormaps by linearly spaning between two or more colors by name.
