This is indeed an agg problem. It is not a limitation in the sense of
'n is too large'. It looks like a bug in agg but it is too early to
For example, this is OK
>>> plot(n, 'o')
Ie, the problem seems to occur when plotting solid lines where many of
the y values are similar, but is not a problem with the length of n,
I was able to reproduce the bug in pure agg c++ and posted to the agg
mailing list. Maxim (agg author) is on vacation, but I suspect he'll
provide some insight when he returns.
Thanks for letting me know,
