You can get the tick text strings (see below) and see how many of them
there are. A better solution, while more complicated, is to set your
own number of major tickmarks, the data range, etc. Then you guarantee
yourself that you'll always get something logical, but it's more work.

IDLgrAxis -> GetProperty, TICKTEXT = ticktext
ticktext -> GetProperty, STRINGS = strings

Thanks for the response. I took a look at TICKTEXT it works fine if you
want the user to create values that they want shown. However, the number
of values you enter have to be the same lenght of the number of major tick
values that are present. How do you find this number of major tick
values?
Another thing I had a question on is if you can get the string of numbers
from TICKTEXT using GetProperty. The reason I want to do this is so that
I can grab this array of string, convert them to integers, scale all of
them by some value and then set them back to this object? I've had no
luck so far. When I try to get this property, I receive an object and I
don't know how to retreive the array of strings?
Thanks....

I have the same problem with an IDLgrSurface, but I used the TICKTEXT
keyword to do it, that is, I constuct by myself the numbers to be shown.
