%# create multi-colormap, set it to figure To only show a single colormap in the colorbar, you can make use of the fact that the colorbar is simply another plot, which means that you can show only part of it, and change the labels.

If you want to have different colormaps for parts of your surfaces, you need to set the 'CData' property of the surfaces to indices into the colormap. Since you want to set the circled area to a single color only, you can set it's FaceColor property. The image will be continually update with more of the 'blue' spots, the colour should change based on an external value and ideally it will merge colours with the previous spots if they overlap. The Image should not have the dark blue at the top of the mound. If possible I would also like to display a colour bar that represents the colour of the circled area (which will be set by me based on the outside value).ĭoes anyone know of a good way to do this? So the data i have to make these two surfs are two lists of x, y, z points. I am open to suggestions about differant plotting styles ie. Currently I have tried the colormap(gray) function then changing but that changes the entire plot. The outside should be grey scale and the inside should be a single colour based on a value that I have separate to the plot.

What I would like to be able to do is change the colour scheme. The area on the right circled by white is a separate surf function to the remainder of the plot. I have a terrain map which i would like to represent some data in.
