Can matplotlib be run from PythonWin IDE in interactive mode?

Community matplotlib-users

Hi

I'm giving an introductory talk on matplotlib to colleagues next week. I'd
like to run matplotlib in interactive mode from the PythonWin IDE. Is this
possible?

I use PyScripter or occasionally IPython myself, but the python group I'm
talking to have all been set up with PythonWin and my brief is to avoid
confusing then with another IDE.

thanks Eleanor

probably not reliably -- pythonWin IDE runs things inside the same interpreter as the IDE itself, and therefore has problems running GUI code with any GUI that MPL supports.

IPython has smarts to start up MPL in another thread to avoid the issues.

Has pythonWin IDE seen any maintenance in the last five years? It may be time for them to move on!

On the other hand, you can still edit code with the IDE, and start it from a command line.

Hi,

does that mean that it works for you with PyScripter?
Right now the only way to do more than one plot with MPL with PyScripter is to reinitialize the remote python interpreter over and over again.
If you found a way around that I would be glad to hear about it.

To the rest:
Might there be a way to mimick IPython's behavior of 'creating separate threads' (or whatever it might be that makes IPython do the trick) while importing matplotlib? IPython is great but having an editor/integrated debugger with all the other goodies that PyScripter offers PLUS interactive matplotlib-plotting would be even greater...

Cheers,

Thomas

I can get two plots from Pyscripter as follows:
Find out where your matplotlibrc file is

import matplotlib
matplotlib.get_configdir()

'H:\\.matplotlib'

edit the matplotlib file in this directory (or copy the example from the
matplotlib site)to set interactive to True and the backend to one of the Tk
or wx options:

backend : WXAgg
...
interactive : True # see
http://matplotlib.sourceforge.net/interactive.html

make sure there is no # at the front of the interactive line

Choose the matching external Python Engine in PyScripter ie. Run>Python
Engine > Remote (Wx)

Then this example should give two interactive plots:

import pylab
pylab.figure(1)

pylab.plot([1,2,3])

pylab.xlabel('X label for 1st plot')

pylab.figure(2)

pylab.plot([10,20,30])

pylab.xlabel('X label for 2nd plot')

go back and add a y label to the first plot

···

pylab.figure(1)

pylab.ylabel('Y label for 1st plot')
