Modify colorbar in .fig file
显示 更早的评论
Hello,
Is there anyway to rescale the colors in a figure and hence the colorbar?
eg. Right now colorbar is 0.1 to 0.5 BUT I want the colors in the figure rescaled to 0.1 to 0.7.
Is there anyway to do this without replotting the figure?
Thank you, S

Try: caxis([0.1 0.7])

+1, You're right, this is probably more what sas0701 is looking for.

figure;
imagesc(magic(20));
h = colorbar;
pause %pause so you can see the change on the next line
set(h,'ylim',[30 60]);
Like this?

I tried it by opening a saved figure which had a color bar on, and it worked for me. But maybe you could try what Sean wrote, though you'll have to find the handle of the color bar yourself:
someone smarter than me might know a quicker way, but to get started you can do H=get(gcf,'children'), and find which one of those has the tag 'Colorbar'

h = findobj('tag','Colorbar')

What do you mean by rescaling - relative to what? Do you want new colors? A picture of the figure might be useful

CLim is the property of an axes; so get the children of the figure, and modify the clim property of them using set()
