[ncl-talk] remove white space in panel plot

[Xi Chang]

Hallo,
Im creating my panel plot not using gsn but using these functions:

  xres at vpHeightF
  xres at vpXF
  xres at vpWidthF
  xres at vpYF

after save the figure in pdf format i found too many white space below my
panel plot. Any idea how to remove this extra white space? It doesn’t work
with

system("convert -density 88 -trim
"+pltPath+"."+pltType+""+pltPath+"."+pltType)
