[ncl-talk] irregular (explicit) but equally-spaced axis

[Adam Phillips]

Hi Yanting,
I believe the behavior that you are after is NCL's default behavior when it
comes to axes. I've modified Applications example axes_1.ncl, and attached
the script and resulting plot here. As you can see, the distance between 0,
2, 10, 30 and 100 is equal. See other examples on the axes page here:
http://www.ncl.ucar.edu/Applications/axes.shtml

Hope that helps. If you have any further questions please respond to
ncl-talk.
Adam
