Re: skewT

I would have thought the following would do it.

[snip]
       xWind = skewtx (58. , skewty(presWind(0)))
       sx(0:npres-1) = xWind ; "x" location of wind plot
       sy(0:npres-1) = skewty(presWind)
       gsn_polyline (wks,xy,sx(0:npres-1),sy(0:npres-1),gsOpts)
       gsn_polymarker (wks,xy,sx(1:npres-1),sy(1:npres-1),gsOpts)
[snip]

Not sure what to say.
