[las_users] Dataset Remembers Vector Configuration

[<John.Schattel@xxxxxxxx>]

Hi All,

I have an LAS running which had one vector defined using the u and v 
variables (surface current) in a dataset.  The dataset I am using also 
contains variables u_air and v_air (components of the wind).  So I 
added another vector definition to the dataset .xml file.  I then 
changed a custom script that was only plotting u and v so that it would 
only plot u_air and v_air.  Finally I performed a make to rebuild the 
LAS.  The new LAS showed both vector check boxes.

Of the five files (datasets) that you can click on in the LAS, the ones 
that I had previously clicked on (had seen the u/v vector 
configuration) would still only produce surface current plots 
regardless of which of the two available vector check boxes were 
selected.  When I clicked a file that had not been clicked on, I could 
get the wind vectors to plot.  When I changed back to just u and v.  
The files that had been used to plot u_air and v_air still plotted the 
wind data.

How is the LAS remembering this configuration information and how do 
I "reset" the relationship between dataset and the vector operations in 
the LAS?

In advance, thanks for any light you can shed on this difficult to 
understand behavior.

John
