Yes. To see this (at least on my platform), you take the example code
and try two things:
1) Comment IN this line: self.panel.Layout(). Run it and you'll get the error.
3) Now comment OUT the tight_layout() call. Run it and you won't get the error.
So you have to Layout() a parent panel (the one the canvas is sitting
on) for this error to occur, but that is a common thing to do in
wxPython when using sizers and shouldn't cause errors. Here is the
traceback:
Traceback (most recent call last):

Settings\user\Desktop\testing_tight_layout.py", line 35, in <module>

ValueError: left cannot be >= right
I just don't understand what this means and why it would be thrown.

WinXP, Python 2.5, wxPython 2.8.10.1 (msw-unicode), mpl 1.1.0 as
downloaded from the site three days ago.
When you say the code runs fine, did you try steps (1) and (2) above?
Also, if you just run it without making those changes, does the
tight_layout() work to resize the plot such that it allows the axis
labels to be seen at all times? (it doesn't for me).
So, to summarize:
- Error if I call self.panel.Layout() before I call tight_layout().
- If I don't do this, no error, but it still isn't doing a proper tight layout.
Thanks,

In your example code, do you see the error raised only when you
include the tight_layout call? Your comments seem to suggest that the
error is raised regardless of the tight_layout call, in which case I
doubt if this has anything to do with tight_layout.
Anyhow, your code runs fine in my installment, linux + python 2.7.2 +
wxgtk 2.8.11.0 + mpl master branch.
On which platform you're running this?
