I am getting a colorbar with uniform color. I want there to be variations so the distribution makes sense.

The P matrix varies from 1 to 2, however the returned figure shows one square with one uniform color. it would be a great help, if i could have a range of colors in that range(1 to 2) to show the distribution.

imshow(P,'InitialMagnification',2000)

colb = colorbar;

set(colb, 'ylim', [1 2])

right now, it shows completely white. for instance if i use 'jet', it shows completely blue.

imshow(P, [], 'InitialMagnification',2000)

[Sattik Basu]

That worked like a charm. Thank you so much.

Hi Walter, where do i input to get the 'jet' color scheme, its not working there anymore.

[Walter Roberson]

colormap(jet) after the imshow() call.

Or... you could instead

imagesc(P);
colormap(jet);

This will not mess up nearly as many settings as imshow() will.

That imagesc command worked. thank you again.
