I don't know if this is helpful or not but here is what I get
(ubuntu 8.04, sage-3.3.alpha1):
sage: import pylab
sage: pylab.clf()
sage: pylab.figure(1)
<matplotlib.figure.Figure object at 0x69e9150>
sage: xs = range(1,10000,100)
sage: pylab.plot(xs, bits24_original, label="$S_n$")

sage: pylab.legend(loc=2)
/home/wdj/sagefiles/sage-3.3.alpha1/local/lib/python2.5/site-packages/matplotlib/axes.py:3590:
UserWarning: No labeled objects found. Use label='...' kwarg on

warnings.warn("No labeled objects found. Use label='...' kwarg on

sage: pylab.ylabel("iterations")
<matplotlib.text.Text object at 0x6dd7d90>
sage: pylab.xlabel("x")
<matplotlib.text.Text object at 0x6ddaa90>
sage: pylab.grid(b=True)
sage: pylab.savefig('/home/wdj/sagefiles/graph.svg',dpi=1000)
It saves a graph with labeled axes but no plot. I don't understand the error
messages (either for your code or for mine) produced though.
