I did this sort of thing using function graphics. In my case, I did a histogram of the frequency with which certain words appeared. I then sorted the words according to their frequency and plotted this in a barplot type histogram. This works however also for a simple plot().
Basically it is something like this:

xx = findgen(10)
yy = findgen(10)
pp = plot(xx,yy)
pp['xaxis'].tickInterval = 1
tn = pp['xaxis'].tickname
for i=0,9 do tn[i]=string(byte(i)+97b)
tn[10] = ''
pp['xaxis'].tickname = tn

Something like this was shown a few days ago on the newsgroup and I found it really nice. I think it was Pablo P.

Cheers,
Helder
