Hi Martin, I suggest upgrading to 0.87.3. I can run your test script and can open the resulting eps file. Please note, however, that you are asking for a file that plots 2e6 points. We have already optimized the postscript commands such that each marker or line requires essentially only a single line of postscript code (a great improvement over mpl version 0.87.2), but that still means that we need to write 2e6 points x 18 bytes per point ~ 36 MB (it actually ends up being 41MB), and postscript then has to interpret that massive file. This yields about a factor of 5 improvement in the size of your file, and its about the best we can do for postscript.
If you want a smaller file size, I suggest you convert your file to some other format, since most of your data points lie on top of one another, and then convert back to eps if you really need that format. For example, you can convert your 41MB eps file into a 274KB pdf file or a 6KB png file. Finally, we dont include tiff previews in our eps files, so this is not a bug.
