*fftplot* - Plot power vs. frequency

  xt> fftplot

  input table file: rp90_fft
A plot of Fourier coefficient value vs. frequency will appear on screen. To make hard copy, type = with cursor within plot, to return cursor to command window, type q.

Note: The plot is set to autoscale and will display the largest coefficient. To better display smaller coefficients, change the parameter file to specify exactly the limits of the y axis, e.g., from 0 to 2 (assuming you are plotting ``normpower'' for a large number of bins).

fftplot y_range = ``0 2''
