Change how numbers are visualized with imagesc?

Hi, with

figure,imagesc

I visualize the scale like "scale"

but I want to visualize with "0.02, 0.015, 0.01 ..." without "x10^3"

What can I do?

Multiply your image by 1000 before passing in to imagesc. A side effect though is that the pixel values reported by mousing around over the image will also be 1000 times as big (rather than the original values) if you called impixelinfo, but maybe that will be OK. I prefer imshow to imagesc since it doesn't apply some (probably undesired) colormap by default.

scaledImage = originalImage * 1000;
imshow(scaledImage, []);
colormap('turbo');
colorbar;
impixelinfo

Multiply by 1000 doesn't solve my problem. I don't want the scale "(20, 15, 10, ...)*10^-3" but the scale "(0.02, 0.015, 0.010, ...)".

If I multiply by 1000 I will have the scale "(20, 15, 10, ...)" that it is not what I want

Make up your own custom labels. See the documentation

help colorbar properties

Set TickLabelsMode and TickLabels properties for the colorbar.
