[ncl-talk] TickMark resources

[Laura Fowler]

Hi Adam:

Thanks for the quick reply. I was actually looking at that example over the
week-end. I think that I misunderstood that res at tmXBValues were supposed to
be values of latitudes. I thought they referred to the indexes of the array
that contained the latitudes.
Thanks,
Laura
