Adam,

The x tick mark spacing is set by the grid point spacing in the grid file.
If you are doing a zonal cross section, then the ticks would have an even
latitude interval if you are on a lat/lon grid. Otherwise, there is no
way to change the tick interval.

There is no builtin function for creating a vertical average.
You can set up a script to do the computation in gddiag if you
know all the levels you have data on.
