Hi
I am having a problem with your solutions, I think it is a problem with my computer system.
- I have first run your program with the two subplots (imagesc and pcolor), and that work fine,
- Then I have copied your last program (with the three subplots, imagesc, pcolor and alpha), and I get the figure with the labels and title reversed (as I had put a mirror above the title).
How can I fix that problem?

Thank you in advance for your help.

Camille.
