No. IBM (this is a thinkpad) has installed a python in c:\ibmtools\python22
I'm guessing they use it for some kind of maintenance.
Up to now, it's existance has been almost entirely benign, except for a 
warning I get when starting ipython. There's an issue somewhere with 
the case of the file fcntl.pyc (vs FCNTL.pyc) and/or the pythoncaseok 
environment variable. I swatted it down a couple of times, but it keeps 
coming back. I realize that things aren't exactly as they should be, 
but nothing has broken ... yet.
IBM has set pythonpath for me:
C:\Documents and Settings\Gary>echo %pythonpath%
C:\IBMTOOLS\utils\support;C:\IBMTOOLS\utils\logger
However, if I un-set %pythonpath% I still can't import pylab. (No 
change in behavior)
%path% references c:\ibmtools\python22, but only after all the listings 
for c:\python23. AFAICT no other environment variable references the 
IBM python.

Thanks for your help on this. Since I appear to be an isolated case, 
shall we take this off-group?

After some more diligent searching I have the title, and 
axis labels working. I also have concluded that when embedded,
I will have to explicitly add and control something like the 
toolbar that appears in non-embedded mode. Any hints as to 
how to access the icons, etc would be helpful. I believe 
I have found most of the methods in the matplotlib interface
as distinct from the pylab interface. These would be panx, 
pany, zoomx, zoomy, zoomx, and zoomy. Somewhere, not yet
sorted out, is a way to save a figure when embedded. 
As a newcomer, that distinction between pylab and matplotlib
per se, was confusing to say the least.
Apparently there is much overlap but also some conflict when 
embedding in a GUI to add various controls. It is all rather
exciting but yet confusing at the same time. After 41 years
in software development, I get to OOP and Python!! 
Most of my usage has and will be Fortran but I have 
a smattering of C (a few months on an 8-bit machine), a log of
PL/1 a long time ago, some PDP 8-I assembly, and Basic. 
I have not used C++ and do not plan to do so.

I have been making good progress in creating a simple plotting
package for time series read from files. I would now like
to embed this into TK. Using some extrapolation and even
a bit of guess work I have cut and pasted material from 
.../examples/embedding_in_tk.py and have a nice window
popping up with a quit button and part of what I want. 
The axis labels are missing and so is the toolbar-items
that need to be present. How does one add labels for 
the x and y axes as well as get the toolbar to appear
in the example: embedding_in_tk.py? They both appear 
when the non-embedded script is run.
I have searched the examples and tried sever val options
but nothing works. Why the toolbar appears in one
case but not the other is currently unclear to me. 
Quite impressed with matplotlib but the learning 
curve is steep and I am feeling my way 
along a tortuous cave in dim light!!
