does any one know how to plot wind vector in a timeseries form

[Eric Altshuler]

Hello Fang,

Here is a trick from the grads documentation on graphics output types (http://grads.iges.org/grads/gadoc/gradcomdsetgxout.html). I'm not sure why it's done this way, but it seems to work:

To draw a 1-D time series with graphics output types vector or barb, set the dimension environment so that only time is varying, then :

      display const(u,0); u ; v

So you should have all dimensions fixed except time, with X, Y and Z set to the values you want, set gxout to 'vector', then execute the above command (assuming your wind variables are named u and v).
