I use "DPLOT" www.dplot.com It won't show you real time graphs, unless you
write your own capture software (VB) which is very doable. If you are
running a capture, and then break the data out into dplot, it can do allot
of computation for you, fft dft, etc... Capture can be in many different
formats, including "comma-separated-values (csv)". It's worth a look, around
$30 for full version, Dplot jr is free.
