These bugs may have been caused by a change in version of matplotlib after 1.1 was released, I am not sure. Anyhow, to make this work correctly, you need to go to     C:\Python24\lib\site-packages\fipy\viewers\matplotlibViewer\matplotlib2DViewer.py and change line 83 from     >>> self.colorbar = pylab.colorbar(array(self.vars[0])) to     >>> self.colorbar = pylab.colorbar() while you are at it, you may want to edit matplotlib2DGridViewer.py, line 111 (not necessary to fix the above, but worth doing) from:    >>>  return reshape(array(self.vars[0]), self.vars[0].getMesh().getShape())     to    >>> return reshape(array(self.vars[0]), self.vars[0].getMesh().getShape()[::-1]) to make that work correctly as well. Sorry for the hassle. Viewers are hard for us to get right as they are not included in our test suite. We will most probably release an update version 1.1.1 with the bug fixes to the viewers.
