> I am plotting the 3D flow trajectory from WRF output. I followed the

> 
> 
> The animation on that webpage shows the trajectories start at a lower

> trajectories start at all levels, no matter what level I choose.
> 
> What I do is: Formulas->Grids->Create 3D Flow Trajectory->Trajectory
> Colored By Parameter, and then choose u, v, w, and pressure as s and s0.
> I tried to use the level=1, level=all or level=several levels, it seems
> not much difference. I use one time (start time) and one level (start
> level) for s0. It would be so much appreciated if you can provide me any
> suggestion.
