Hi,

I have been wondering about how to create a custom colormap, with a dynamic range similar to the default colormaps in MATLAB. The call to the colorbar will be something like,

customColormap = getCustomColormap(nColors);

It is possible that there is no clear solution to this problems, but it would be great if anyone have an idea to how to proceed.

Best Regards Patrik

Hi!

You can use the command "colormap" to create color maps. The built-in colormaps can be scaled dynamically, like

colormap(jet(nColors))

You can as well build your own color maps. A color map is a m-by-3 matrix of real numbers between 0.0 and 1.0, specifying RGB values.

Thank you this colormap editor is amazing. For the automatic rescaling I guess i gets more complicated the more advanced colormap, but thank you for giving me a start.
