Why doesn't the save button work on a matplotlib plot?

Question

I have matplotlib 1.0.0 installed in a Python 2.7 virtualenv on Mac OS X 10.6. I can create plots fine. However, whenever I press the Save button, I can\'t type tex

Answer 1

For those that Thouis method didn't work:

I noticed that a simple work around is to change matplotlib backend. Here is a list of available backends:

http://matplotlib.org/faq/usage_faq.html#what-is-a-backend

Note that you should choose one of the renderer ones (i.e. the ones that support show() command). You might need to install the backend, but you might have multiple ones installed.

To do so:

import matplotlib
matplotlib.use('Qt4Agg')    #replace 'Qt4Agg' with desired backend

Warning: This should be done BEFORE importing pylab, etc.

Answer 2

My answer doesn't fix the problem but can workaround it easily! You can touch a new file with the correct file extension in a terminal. After you can choose this file with the mouse inside the matplotlib window and overwrite it.

Answer 3

You need to convince OSX that the virtualenv is actually running from an Application Bundle. Fix discussed here:

And implemented here:

Answer 4

To solve this:

Use conda install python.app to install pythonw.

Then use pythonw instead of python in your terminal.

E.g.

pythonw my_plot.py

Hope this helps
