Re: X-values not shown in zonal mean plot

Hi Julianne,

You don't have much control over that zonal means plot when you
create it use the gsnZonalMeans resource.

To have more control, you can use the gsn_csm_attach_zonal_means
function. This allows you to set whatever
resources you'd like for the zonal means plot.

Please see example 7 at:

http://www.ncl.ucar.edu/Applications/zonal.shtml

This will show you how to force more tickmarks.
