Hi matplotters,
I am trying to create an image and save it to pdf.
Unfortunately, the result is much different if I save it to pdf, eps or png.
I am on Mac OS X 10.4, using qt4 4.5.0 and the qt4agg backend (but the problems also occur with -dmacosx).
The plot I am trying to make is an overlay of hists + datapoints with errorbars.
The png roughly looks like I would expect (although I can’t figure out how to plot a straight black horizontal line at y=0. pylab.plot doesn’t seem to do what I want)
The eps doesn’t get filled with the correct colors, and the pdf and the svg don’t work at all.
The error message for saving as svg is inlined below the message.
The rest of the files should be accessible at https://jstrube.web.cern.ch/jstrube/matplotlib_testcase/
You need the python bindings to CERN’s ROOT libraries if you want to reproduce the plot.
Any help is greatly appreciated.
Cheers,
Jan
