Hi, I have an axes displaying image data inside a panel, which is the parent of this axes.

Now I would like to create a colorbar for this image data outside of the panel which surrounds the axes. Is there any way to link the colorbar not directly to the axes but to the panel, so that

set(myColorbar, 'Location', 'eastoutside')

will result on my colorbar on the right of the panel (instead of on the right of the axes, but inside the panel, as it is behaving now)?

I would be interested in general approach, where the data for the content of the colorbar (e.g. the colors itself) would maintain associated with the axes to reflect later changes and the position & size of the colorbar will be associated to the panel.

Thanks in advance for any help

That is easy, when you create figures and plots, you can grab the handle and then you can modify its properties:

a = rand(64);
imagesc(a)
h1=colorbar;

We have now grabbed the handle of the colorbar, and one property is the position:

h1.Position
ans = 1×4
    0.8284    0.1109    0.0381    0.8152

Now, you only need to set the position to whatever you need:

h1.Position=[0.4 -0.2 0.05 0.6];

unfortunaly this does not work in my case, since the Axes is contained in a Panel and setting the position with negativ values outside of the panel lets it disappear.

I am not sure if we can simulate the panels here, but I can move the colorbar of a second plot to be on top of the first plot:

h0=gcf;
h1=subplot(121);
imagesc(rand(64));
hc1=colorbar;
h2=subplot(122);
imagesc(100*rand(16));
hc2=colorbar;
hc2.Position=[0.12 0.1 0.02 0.8];

We can also modify the position of the individual axes:

h1.Position =[0.2 0.3 0.2 0.3];
