Is there an easy way with the Pylab interface to add an arc to a plot?
 I need to label an angle on a plot.

Thanks,

Ryan

_.get_rgb() is a mistake, I've changed it to gc.get_rgb().

Using the latest cairo (git), pycairo (cvs) and matplotlib (svn) and
running examples/simple_plot.py I get a 22K PDF file. But when I try to
view it with evince and xpdf I get "unable to open document" type
errors.

The matplotlib cairo PDF backend relies on the cairo PDF backend.
The cairo PDF backend is relatively new, and is still being developed,
and I believe it currently only supports a limited set of fonts.
