I think, it would be good to improve the routines when doing FFT analysis of the data.
There should be more user's choice for the output in real, complex, phase...for the FFT transformed data.
It checked this with Igor Pro and Origin as well the data handling and their output was much better.
Is there a general routine in GSL which Scidavis is using?
Thanks!

    SciDAVis creates a hidden table (accessible via the project explorer) with all the information you're asking for, though only the amplitude is plotted. It would be nice if those could be selected for plotting right away, so I'm leaving this open as a feature request.

    And yes, the implementation is based on a GSL feature.
