I use octave (a matlab clone) for plotting, it comes with most linux
systems:

octave:2> plot([1 2 3 4], [-1 -2 0 1])

will plot the line line described by the two vectors [1 2 3 4] (x axis)
[-1 -2 0 1] (y axis).

It doesn't have a mouse interface for zooming.  However it can format
plots nicely and you can add arbitrary code to process the waveform (for
example scale, or extract and plot just the parts you want to see).

Say you have a big vector x, you can extract just a part of it like this
x[1000:2000].

I have used Octave (and Matlab) for lots of modem and speech signal
processing work.
