Re: Skew_T color

Hi Dennis:   Thank you very much for your help!   Actually, I tried Example 4 already. The locations of the two wind profiles are coexistent. Then I set dataOpts@xpWind    = 40 for one sounding and dataOpts@xpWind    = 30 for the other.   However, both locations are still at 45, which means that dataOpts@xpWind  does not work for me. The location of the wind profile is always at 45 no matter what number I set.   Would you please tell me the reason and how to solve this problem? Thanks!   Regards Ed ----- Original Message ---- From: Dennis Shea <shea@ucar.edu> To: Yang Yang <yang123yang@yahoo.com> Cc: Mary Haley <haley@ucar.edu>; ncl-talk@ucar.edu Sent: Tuesday, June 10, 2008 10:36:42 AM Subject: Re: Skew_T color Please see Example 4 at:  http://www.ncl.ucar.edu/Applications/skewt.shtml Note the following line in the example dataOpts@xpWind    = 40.      ; new location for winds [default 45 Yang Yang wrote: > Hi Mary: > Thanks! > May I ask you one more question about Skew_T? > I tried to set xpWind for different numberd from 45 in the script.

If this is the case, can you tell me how to make necessary changes so that different number setting for xmWind can be accepted by skewt_func.ncl?

I used  Version 4.2.0.a033. Is the version not high enough? or my default colour table is different? Would you please help me solve this problem?
