Re: skewT

I changed xWind (the x location of the vertical bar) and xpWind (the x location of the wind barbs) to 29 from what they were (about 24).  But now they are running into the Height(km) vertical bar.  When I up xWind and xpWind to 30, the barbs plot, but the vertical bar does not.  What I'd like to do is move the vertical bar and their associated wind barbs out to about 31- that way, when the winds swing due west, they won't run into the temperature/dewpoint plot (but again, when I set xWind and xpWind to 31, only the wind barbs plot).  Then move the vertical height  bar to the right of that.  Where is the x-pos value set for the vertical height bar, and any idea why the vertical bar for the wind barb blots is disappearing when I go above the value 29? thanks, Steve ________________________________ From: Paula Doubrawa Moreira <pmoreira_at_alaska.edu> To: steve kirby <thin_runner_at_yahoo.com> Cc: "ncl-talk_at_ucar.edu" <ncl-talk_at_ucar.edu> Sent: Monday, August 29, 2011 1:31 PM Subject: Re: skewT The barbs disappeared because 60 put them out of the viewport. Try a small number. If you want the line to disappear or be in a different location, change lines 633 and 634 where the procedures gsn_polyline and gsn_polymarker are called.
