Color bar positioning problem

 <<SnagIt1.png>> Hi all!

I'm trying to position a color bar on my plot using NDC coordinates. The
color bar seems to shift around rather unexpectedly with changing the
label font size (see attached png). Is this a bug or a feature? If the
latter, how can I manage to position my color bar exactly in NDC
coordinates?

Thanks,
Oli
