> Hello -
>
> Our student tester found a bug with the "3D Volume Vector" display type where
> if you change from "All Levels" to an individual starting level (e.g. "200
> hPa"), and then back to "All Levels" the trajectories disappear.
>
This should be fixed in tomorrow's nightly release.
> Note that I can't test this with the new "3D Grid Trajectory" display type
> because "All Levels" isn't an option under the Trajectory Start Level menu.
> Should this be there?
>
This is not in my design, we need more discussion in our next telconf.

> Easy way to replicate:
> 1. Create data source for most recent NAM 80km CONUS
> 2. Display '3D grid > Derived > 3D Flow Vectors' with the '3D Volume
> Vector' display type (all times, entire domain).
> 3. Change to Trajectories in the Layer Controls/Displays tab
> * At this point, trajectories at All Levels are displayed
> 4. Change to an individual level, such as 200 hPa.
> * This works as expected
> 5. Change back to 'All Levels'.
> * There are no error messages, but the trajectories disappear
>
> Note that this can't currently be tested in the IDV with the new "3D Grid
> Trajectory" because "All Levels" is not an available option in the Trajectory
> Start Level dropdown.

> If you click back to 'Vectors' and then to 'Trajectories,' it defaults to

> Regarding testing of Inquiry 2360, I had the same issues when plotting the 3D
> data as Matt did on both OSX Intel and Linux 64 (Eugene). The behavior was
> the same for different displays too (i.e. 3D volume vector, 3D volume vector
> colored by another parameter, etc.) I also had some issues with 'xy skip'
> when testing the 3D data. When changing the 'xy skip' in a specified level
> and going from that specified level back to 'All Levels' the trajectories
> disappear. This occurred on different displays and different datasets. The
> datasets tested were GFS 2.5 degree and GFS 90km CONUS.
