[IDV #OWY-715558]: difficulties plotting vector field



Austin,

What is it you are trying to do? If you are try to plot flow vectors, this can
be done easily by setting up IDV parameter aliases.

In the field selector, right-click on the Eastward Water Velocity. This will
allow you to set up a parameter alias. You can hack it by selecting an alias of
U wind component. Do the same for the V field. At this point reload the data by
right clicking on the Data Source in the Field Selector. This will make a
"Derived" node under 2D fields. From there, you can plot your flow vectors.

Best,

Unidata IDV Support
