[Matplotlib-users] Colorbar labels never appear vertically

[James M. <jam...@gm...>]

Hi,

I am having a problem where the colorbar labels will never appear
vertically, even when their rotation is specified as "vertical". As you can
see in the screenshot here: http://minus.com/lbOJyOljH  this creates
problems when the labels are cut off and generally looks unprofessional.

I am creating the colorbars with code like:
        cbar1.set_label("Lifetime [$\mu$s]", rotation='vertical')

And yet the specified rotation has no effect.

Any help would be much appreciated,
James
