something GtkCurve/GtkDataBox like

[Paul Davis <pbd op net>]

i'm trying to find a widget that would allow me to display curves
whose total length is vastly greater than will fit into the window at
one time. the curves are defined by a series of (x,y) coordinates and
i want to be able to add new points, move and remove existing ones,
zoom and scroll.

i have widgets that do this for audio waveform data; here, the data
density (points per unit of real-time) is much lower than for audio
waveforms, and it seems a little expensive to use the same widget.

comments, thoughts ?
