meteogram for station data

Hello,
1) Does any one have a meteogram for station data that he or she is willing to share?
The example on the NCL page uses model data.

2) I wish to plot the wind (i.e.) over time for a given station. The station obs has
the following

       int DIR(recNum) ;
                DIR:long_name = "Wind Direction" ;
                DIR:_FillValue = -99999 ;
                DIR:valid_range = 0, 360 ;
                DIR:units = "degrees" ;
        int SPD(recNum) ;
                SPD:long_name = "Wind Speed" ;
                SPD:_FillValue = -99999 ;
                SPD:units = "" ;
How do I combine the two variables above so I can plot it. For example, if it were
model data, I will have to use the uwind and vwind to get the vector.
Then I can do this
windlayer = gsn_vector(wks,ugrid,vgrid,uv_res) for a given layer.

Here I only have surface data for the station. I want to plot the surface winds
over time.
Any help will be appreciated.

Thanks
Ben
