Real-time graphs

[snrkiwi-lists at yahoo.com]

I've trolled the lists, FAQs, and Net as a whole, but
can't find anything definitive to answer this.

We're looking for real-time graph capability (bar,
line, etc), so that we can display telemetry from a
robot system.  There are a bunch of packages out
there, but many seem to provide only static graphs
(e.g. for scientific, financial data, etc). Does
anyone currently display real-time telemetry using
Python? Can anyone provide any suggestions?

TIA
