MATLAB: GUI multiple axis different color map

axescolormapgui

Hi,

Currently i'm using several axes in one single gui to plot several image results, but whenever i plot using imshow() and then i plot something else in a different axis with surf() or imagesc(), all of the axis stay in the same colormap (gray scale) even though i set a different colormap for a specific axis

cant find a way to use different color maps for specific axis, because everytime i set a new colormap for a specific axis all the axis in the gui change to the new colormap instead of holding the specific colormap i've assigned.

Can anyone help me out ? Thx

MATLAB: Unevenly Map Data to an RGB Map

When you use a colormap, the entry-number used always scales linearly between the upper and lower limit established on the color axes (caxis) .

One approach is thus to create a colormap that conceptually spans the entire range of your data, but you repeat colors in the upper 1/3 (or as appropriate). It is completely valid to use a colormap that goes something like

black
red/8
2*red/8
3*red/8
4*red/8
yellow
yellow
yellow
blue

If you are using a sufficiently old MATLAB on MS Windows then you are limited to 256 entries in a colormap; other operating systems and newer MATLAB for Windows permit 65536 entries.

Another approach is to do the color mapping yourself. You can, for example, discretize() the Z range to get bin numbers, and ind2rgb(binNumbers, your_color_map) to get an RGB image. You can then set that as the CData of the surf() -- though I find that texture mapping like this is often easier to accomplish using warp() instead of surf() .

MATLAB: How to change color bar limits in imagesc

You can do that task by setting CLim of the axes, like:

figure
imagesc(rand(4));
ax = gca;
ax.CLim = [0 1];
colorbar
