I'm working on an app that has 8 axes per figure (X1, X2, Y1 ... Y4) and it works fine. Well, the MPL bits do. One of the unexpected things that we had to do in order to get the multiple plots to work as expected was to ensure that each additional subplot had its own label. MPL has some 'helper' code that tries to consolidate the axes so that if you create two axes with identical parameters, you only end up with one axes object (I think -- someone more knowledgeable can fill you in on the details). Now, we do things using the API rather than using pylab, some I'm not entirely certain (and haven't tested it) but I think that the pylab command 'axes' has an optional argument of 'label', which you should set to be a unique string for each subplot. I've only scanned through your code, and I'm not at all familiar with the pylab syntax, but I'm puzzled that you haven't used twinx (or in API parlance, sharex) anywhere. Regardless, the API code for overlaying subplots is of the form: figure.add_axes(axes1.get_position(), sharex=axes1, frameon=False, label='someUniqueString') Hope this helps, Anthony. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
