spectro_plot is a good routine but seems to have a touch of odd
behavior (I didn't know about this routine before)

odd behavior:
;; setup some data
dat = dist(100)
;; x is just 1:100
x = findgen(100)
y = findgen(100)
;; y has a datagap at 49 by 100
y[50:*] += 100
spectro_plot, dat, x, y, /no_ut
END

I would expect the plot to have a 100 unit gap in y but instead I get
oddness.

Have a look,

Cheers,

Brian
