Hi Jonathan,
I asked Dave Brown, one of our NCL developers, about this, and he
came back with a full script showing an example. I modified his
example to use gsn_xxxx functions and to create some dummy data.
This gist of this example is that it uses some tickmark resources to
allow you to change the labeling to a log base-2 axis. Please see the
attached script and PS file and let me know if this is not what you're
talking about.
