Hatched fill pattern using colormap

Hi all,

I have a code which generates a plot where the source is a matrix. Each position contains one value from 0 to 3 (included) depending on a previous algorithm. Then, each value is represented by a singular colour (custom defined). I would like to substitute colors by hatched pattern. For exemple, 0-black 1-// 2-\\ 3-// and \\. I'm using the colormap function.

Could somebody help me?

Thanks.

BR,

Raúl.

color mapping cannot generate hatched patterns.

Thanks Walter. Any suggestion about how to do it using another toolbox?

Thanks!

Other than the bitmap-based options, these still don't handle legends well (or at all), unfortunately...

ADDENDUM

For potential others who may find this thread in future -- I've posted patches to hatchfill on File Exchange which seem to work for the limited testing done. Should at least be trail of bread crumbs to resolve any other issues remaining.
