[Matplotlib-users] xticklabels printed twice when using twinx

[Christoffer A. <Chr...@fk...>]

Hi all,

I have noticed a funny behaviour when using twinx to do two plots on the
same axes: the xticklabels are printed twice, once for each axes. This
shows up as slightly thicker labels than for a single axes. It is
particularly visible for ps or pdf output, but can be seen also in an
interactive session.

I can also see this in the figure shown for the two_scales.py example
(http://matplotlib.sourceforge.net/_images/two_scales.png), where the
xticklabels are thicker than the yticklabels (though it is not so
apparent due to different colours. I therefore assume it is not just my
installation. (Adding

for tl in ax2.get_xticklabels():
    tl.set_fontsize(16)

just before the last plt.show() in two_scales.py makes it even more
visible)

Does anyone know of a reasonable work-around? Surely it is not the
intended behaviour?

Thanks for any help,
Christoffer Åberg
