Can you try building matplotlib 0.99.1.1 from the tarball, rather than the gentoo package? That would help to rule out any of the gentoo-specific changes. Nothing in the portage leaps out at me as problematic, but we should rule that out. Mike Paweł Rumian wrote: 2010/1/15 Michael

OK, I've done more tests. The problem occurs always when plotting data from masked array with lines. When there is a masked field in the array, drawing is stopped, and so if the first element is masked, no output can be seen. When all fields are unmasked, there is no problem. Also, drawing with

Does this example work for you? http://matplotlib.sourceforge.net/examples/pylab_examples/masked_demo.html I don't have scikits.timeseries installed, so I can't confirm whether your original attached example works or not. Can you produce a standalone example that reproduces the problem?

I'm not sure what the cause may be, particularly since I can't reproduce it myself with matplotlib 0.99.1.1. What backend are you using? Agg, Cairo and Wx all check out for me. The examples you point to don't look like Agg output to me... Do you have anything in your matplotlibrc? Mike
