[ncl-talk] Two bar in one plot

[Adam Phillips]

Hi Ipshita,
Take a look at example #9 here:
http://www.ncl.ucar.edu/Applications/bar.shtml#ex9

You will want to adjust your months array in your two
gsn_csm_xy calls to be different from one another as it is done in the
example.  Otherwise your bars will overlap.

Good luck,
Adam
