I'd like to use the data cursor for pseudo color plots created with pcolor. I wonder how the arrow keys work in this case. If I press the arrow up/down key, the cursor moves one point up/down as I expect it. However, if I press the arrow lft/right keys the cursor seems to jump more diagonal than left/right as I would expect it.
Does anybody know the reason for this? Is there a way to overcome this behaviour and let the cursor move horizontically as well?
P.S. I'm working with R2010b.
