Re: Contour effects

Hi Guilherme,
Thanks for sending an easy-to-run script so we can test it here. Instead
of using gsnAboveYRefLineBarPatterns/gsnBelowYRefLineBarPatterns, I
believe you need to use gsnXYBarChartPatterns2.
http://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnXYBarChartPatterns

gsnXYBarChartPatterns2 will assign patterns sequentially regardless of
the orientation of the bars with respect to the reference line, while
the gsnAboveYRefLineBarPatterns resource repeats the patterns but for
only those bars above the reference line.

So comment out these two lines :
;res@gsnAboveYRefLineBarPatterns =
(/seco,seco,seco,seco,seco,seco,seco,umido,umido,umido,umido,umido/) ;
12 meses
;res@gsnBelowYRefLineBarPatterns =
(/seco,seco,seco,seco,seco,seco,seco,umido,umido,umido,umido,umido/) ;
12 meses

and add this line:
res@gsnXYBarChartPatterns2 =
(/seco,seco,seco,seco,seco,seco,seco,umido,umido,umido,umido,umido/) ;
12 meses

Finally, you should add a frame(wks) call right after your gsn_panel
call, as you are setting gsnFrame to False in your panel resource list.
I have attached a modified version of your script along with the
resulting graphic.

Hope that helps,
Adam
