I actually had 2 simultaneous problems, and it took me a while before I
managed to solve them simultaneously:
- my oplot'd vectors were off the y scale - I forgot that I'd created
them as the plotted vector *minus* a best-fit straight line
- if I didn't use the x argument in oplot, y was plotted as a function
of point number (RTFM ...) and was way off the x scale.
Thanks for the helpful suggestions. Now I can get back to guessing how
FFTs and wavelets work. Guess, plot, guess, plot - isn't IDL wonderful?
