The funny thing is that I can import pyqtmpl from the command line and make a figure with subplots and have no problems. That is, the figure will update and I also can keep running stuff from the command line. So, I know it's possible. Somehow.

When I launch from the console, I think PyQt is integrating with the interactive interpreter event loop.

That's why we rely on PyQt to hook into the ipython event loop instead.

So, solving this requires integrating the PyQt event loop with OMFIT's tk event loop.

When using the OMFIT command box to make pyqtgraph figures (no pyqtmpl involved), the same problem occurs. Here's a minimal code snippet you can run in the command box to demonstrate:

import pyqtgraph as pg
from PyQt4 import QtGui

win = pg.GraphicsWindow()
lay = pg.GraphicsLayout()
win.setCentralItem(lay)
ax = pg.PlotItem()
lay.addItem(ax, 1, 1)

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

QtGui.QApplication.instance().exec_()

Closing because pyqtmpl works as well as any PyQt application could work within a tk based framework. The problem has nothing to do with the pyqtmpl wrapper.
