set ccols

set ccols col1 col2 col3 ... colN

Sets specific color numbers for contour levels specified by set clevs.

Usage Notes

1. Contour colors are reset with every execution of clear or display.
2. User-specified ccols won't take effect unless clevs are also set.
3. If any of the color numbers is < 0, it is set to 0 (the background color).
4. (Version 2.0.0+) When using 'gxout shade2' or 'gxout shade2b', if any of the color numbers is < 0, the contour is not drawn (i.e., it is effectively transparent).
5. See section of User's Guide on controlling colors in grads for more details.
