21 ## Create a color colormap. The colormap is red, green, blue, yellow, |
|
|
22 ## magneta and cyan. These are the colors that are allowed with patch |
|
|
23 ## objects using gnuplot 4.0, and so this colormap function is specially |
|
|
24 ## designed for users of gnuplot 4.0. The argument @var{n} should be |
|
|
25 ## a scalar. If it is omitted, a length of 6 is assumed. Larger values |
|
|
26 ## of @var{n} result in a repetition of the above colors |
