Re: text code for overbar?

First, you might want to see example "text_14.ncl" on the text examples page, which was created by Mateus da Silva Teixeira to generate special symbols like the umlaut:

http://www.ncl.ucar.edu/Applications/text.shtml

Creating these kind of characters is not very straightforward to do with NCL, but you can attempt this with the "Hx" and "Vx" function codes. These stand for "horizontal move" and "vertical move".

Here's a sample script:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"

begin
  wks = gsn_open_wks("x11","text")

;---Create a blank plot that we can draw on.
  res = True
  blank_plot = gsn_blank_plot(wks,res)

  txres = True

;---This attaches a "u" with a bar under it
  str = "_~H-15~u"
  txid1 = gsn_add_text(wks,blank_plot,str,0.5,0.5,txres)

;---This attaches a "u" with a bar over it
  str = "_~H-16~~V-21~u"
  txid2 = gsn_add_text(wks,blank_plot,str,0.5,0.7,txres)

  draw(blank_plot)
  frame(wks)

end
