Colorbar labels never appear vertically

Community matplotlib-users

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

Hi,

I am having a problem where the colorbar labels will never appear
vertically, even when their rotation is specified as "vertical". As you

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

I don't understand; even with no kwarg, the label on a vertical colorbar will be vertical. It has been that way for as long as I can remember.

What mpl version are you using?
Please provide a minimal standalone script showing the problem.

I made this standalone script here: http://pastebin.com/AnKeCwiU and this does not suffer from the issue. For comparison here is the plotting function in my program: http://pastebin.com/7xxtPQYb

The only major difference is the use of the interactive display in the script, against the use of Figure and the GTK canvas in my application.

I am using matplotlib 1.0.1

After some testing, it appears to be caused by the use of LaTeX in the labels which then prevents it from being rotated (but only inside the GTK application). I have no idea why this is only occurring when it is not in interactive mode, but I guess for the time being I can just try not to use LaTeX.

The problem is that the Gtk backend does not support text rotation. If you use FigureCanvasGTKAgg instead of FigureCanvasGTK, I think the behavior will be back to normal. The Gtk backend is not fully functional or supported.
