Sure, the commands where it crashes and the output are:
print dates
pyplot.axis([0, len(prices.label[0]), -1.5, 1.5])
pyplot.axhline(-.5,color='r')
pyplot.axhline(.5,color='r')
pyplot.axhline(0,color='.75')
diff = (fisherChained-tornqvistChained)*100
pyplot.plot_date(pylab.date2num(dates),diff,'b-',label='Chained')
pyplot.setp(pyplot.gca().get_xmajorticklabels(),rotation=30)
pyplot.savefig(city+agg+'Diffs.pdf')
