When creating a colorbar to go with a map axes based plot, the colorbar overlaps the labels.

What's the optimal solution for preventing this?

Manually defining the position is hard to figure for a general case and doesn't tolerating window resizing without some sort of callback function being developed.

The root of the problem seems to be rooted in the fact that the map axis objects don't respect the bounds of the parent invisible axis that the colorbar is positioned in reference to.

Simple example. Give the resulting a figure a resize and note how the colorbar overlaps the map axes labels.

fig_h = figure();
maxis_h = worldmap([20 40],[-90 -60]);
colorbar

Hi millercommamatt,

I understand that plotting both map-axes and colorbar result in the colorbar overlapping with the map-axes. Here is a workaround which enables to manually set the position of colorbar:

fig_h = figure();
maxis_h = worldmap([20 40],[-90 -60]);
x = maxis_h.Position(1);
y = maxis_h.Position(2);
cb = colorbar;
a =  cb.Position;
set(cb,'Position',[x+0.79 a(2) a(3) a(4)])
