[Pythonmac-SIG] Using Matplotlib interactive/GUI - How to?

[Louis Pecora]

I installed Chris Barker's compiled matplotlib and it works fine for 
producing a graphics file (THANK YOU CHRIS.  NICELY DONE!).  I've used 
it from interactive, MacPython, and BBEdit (TextWrangler will probably 
work, too, since it's related).

I would like to use matplot lib in the GUI and, most probably, 
Interactive mode.  I've been looking over the documents and examples.  
 From what I've read so far (and I don't pretend to understand it all) I 
have the following two "problems:"

1) I need to install Tkinter.  Attempts to use TkAgg or other things 
warns me that _Tk or some such module cannot be imported or needs to be 
installed.
    Is this right?  Any tricks or  difficulties I need to be aware of  
to do this?

2)  I need to set  the Interactive  flag  in  .matplotlibrc  to  true to 
do interactive plotting.  But I can't find .matplotlibrc in my home 
directory (yes, it should be a hidden file and I looked through the 
hidden files). 
     Where is this one kept on the Mac?  A Finder Find show nothing, but 
I know that doesn't search everywhere.

Is there anything else I'm missing to accomplish GUI and interactive use 
of Matplotlib?

I am running 10.3.8 on a 12" Al PB  1.25 GHz.
