[ncl-talk] plotting help in ncl

[Mary Haley]

Alan is correct about how to do this, and I don't think we actually have
any intentional examples on this.

One thing I wanted to add  is that if you need to do something with the PNG
image, like trim the white space using "convert", then you can use the
"delete" command inside the loop to force a close of the PNG image before
you call convert. This can be really useful if you want to import the PNG
into something like PowerPoint:

plot_names = (/"plot_name", "a_new_plot", "the_plot_strikes_back",
"return_of_the_plot","the_plot_awakens"/)
do i=0,4
  wks = gsn_open_wks("png", plot_names(i) )
  ....
  plot = gsn_csm_xxxx(wks,...)

; Remove white space from PNG image
  delete(wks)
  system("convert -trim " + plot_names(i) + ".png " + plot_names(i) +
".trimmed.png")
end do
