Re: Drawing vector plot with asciii data

Hi,

As Debasish states, you need 2D data to generate vectors. If you have
1D lat, lon, and u/v arrays, then check out the regridding routine,
triple2grid. This puts your data on a 2D grid. No interpolation is
used; it just figures out the closest grid locations:
