Let me add some color to that statement -- when I took a look at your
screenshot, I realized you are using the WX backend and not the WXAgg
backend. If you don't understand the difference, peruse
http://matplotlib.sf.net/backends.html . WXAgg may have the same
problem (and the same solution from my last post) but will give you
more consistent rendering and layout.

Thank you John!!
In fact WXAgg does not have the same problems. I mean, there is no problem
with WXAgg and fig.subplots_adjust(left=0.15, bottom=0.15) is even not
needed! It looks much nicer :

It means that WXAgg is to be the recommend way for embedding in wxpython?

[Matplotlib-users] x and ylabel problem when embedding in wx
I have problem with xlabel and ylabel when embedding in wx. See snapshot :
http://emmanuelfavrenicolin.free.fr/Public/Divers/Snapshots1/wx_snap.png
I put a test code which is based on dynamic_demo_wx.py, adding only the 3
lines :
a.set_title('Title')
a.set_xlabel('Xaxis [u.a.]')
a.set_ylabel('Yaxis [u.a.]')
Just to add title, and label. In this case Ylabel is superposed on ytics
labels and xlabel is hidden by the navigation toolbar.
Do I need twiking and/or understand better wxpython ?
Anyone can help me?
