This is what I meant by the preceding comment: There is an api to 
xmgrace that allows any application written in C to feed values to 
the GUI and make it update the graphs. So the GUI can show the data
while they pour in. The user still has full GUI control over zoom, 
pan and the various aspects of graph scaling. Graphs can be linear, 
log scale, rectangular, or polar. Data points can be all kinds of 
shapes, with or without error margins. No 3D-imaging, though.

Be aware, that there is a down side: The project has grind to a 
virtual stand still since a few years now. The proposed, complete
rewrite that would be grace6 looks like it will never be finished.

You mean some kind of code re-use?
