So if I step through, this clearly does not work in one of my guide-generated GUI callbacks:
imagesc(data); axis xy;
If I step through it, when I get to the colormap function, I can substitute any colormap and run it at the keyboard, and it has no effect. Something has frozen the axes4 image from updating its colormap. However, this above code will change axes1 and axes2 colorbars. I have removed all instances of freezeColors/unfreezeColors calls to avoid any influences from that 3rd party software. Again, I am on 2017a. I hear so much about how this was all fixed back in 2014 in these boards, but that does not seem to be my perspective.
