Hello, While using sage [1], I got problems drawing a line: for some reason, the points with negative coordinates are not plotted (or are plotted on top of others due to an offset problem and thus I cannot see them). I can only reproduce the bug with specific data sets.
I think I could track down the bug to matplotlib, which sage uses to render 2d plots. I included a sage script which generates the data set (in a pickle file), and a python script which draws the faulty line. Usage is : $ sage generate_data.sage $ python test_mpl.py I also included the pickled data, thus you don't need sage at all. I use matplotlib 1.0.0 for python 2.6 on mac os (as provided by macport). Could somebody here confirm the problem, and give me a hint about what is going on? Regards Sebastien [1] www.sagemath.org
