How can I change the minimum value color on the color bar? I'm getting white color for the lower values.
imagesc(x,y,value)
set(gca,'YDir','normal')
myColorMap = colormap;
myColorMap(1,:) = [1 1 1];
colormap(myColorMap);
colorbar;
ma=max(value);
mi=min(value);

You are getting a white color for the lower values because you defined:
myColorMap(1,:) = [1 1 1];

Why does your image have nan's in it anyway? What color do you want the nan's to appear as? I think an axes control might have a background or foreground color that appears if the pixels are nan's (so they mgiht be "transparent") but I'd have to check on that. I never deal with images that have nan's. Why do you have them?

Tunechi — My pleasure!
I A — That’s new. I didn’t know about imagesc until now. I used contourf in my example.
