[IDV #MXT-681298]: Wind Speed Formula Error

Hi Patrick,

I didn't have any issues creating a 2d contour plan view using the wind
speed formula:

* Load each netCDF file into the IDV through Dashboard->Data Choosers
* From the field selector, use the Formulas Data Sources and select Grids->
Speed from 2 components
* Select your u and v fields in the field selector dialog box that appears
* Choose your display
* Click create display

How were your trying to create the wind speed map?

Cheers,

Sean
