[IDV #CZQ-485534]: plotting wave direction vectors

Nikos,

Glad to be of help. I also wanted to mention that we added the flowvector 
formula
to the IDV library. In the next version of the IDV you should be able to use
that formula as a derived field rather than having to write your own.

Best,

Unidata IDV Support
