I would assume this is a quite popular undertaking, so how is it normally done?

I just want to know the approximate area under the curve if all the points were joined by straight lines, no need (or desire) for curve fitting.

If I have to use another graphing program to do this then gnuplot becomes pretty pointless. :p
