[ncl-talk] Wind Legend offset by using “wmsect ”and can't using the search window in the upper right corner of (most) NCL website pages in China

[Adam Phillips]

Hi Bingxue,
If removing the maximize_output line did not work, try adding a delete(wks)
right before the end do:
 maximize_output(wks,pres)
   delete(txx)
   delete(txy)
   delete(xy_plot)
   delete(xy2_plot)
  delete(wks)
 end do

wmvect and other similar procedures are calls to the WMAP plotting system,
an older graphics package that has limitations.
If the deletion of the workstation does not work,  I am not sure a solution
is possible with the current structure of your script.
In that case, you will likely have to alter the script so that only a
single panel plot is drawn.
