HI Paul,
Thanks. I didn't realize it was that simple (appears that doing this
essentially plots everything against integers in x and y). This will be a
good backup plan if I can't get pcolor to work, although as you say, I'll
have to fiddle around some with the axis formatters and such I suppose to
get a good final plot out of this.
Best,
Brad
