Anyone written a gtk strip chart widget?

[Rob Browning <rlb cs utexas edu>]

I was looking for something that creates a display like one of the
procmeter panes or xload when you give it data points.

I have some code I wrote on top of Motif's DrawingArea widget, but I
figured I wouldn't bother translating it if someone's already created
a strip chart for gtk.

Thanks
