Matt, Please upload your newest file with the wave directions to http://motherlode.ucar.edu/repository/alias/idvupload Best, Unidata IDV Support > Sorry for the confusion. When I go to the Waves section (not Momentum) I want > to plot the Primary wave direction (circled in red). That does not give me a > Flow display. It's a vector field (radian values for direction) so I want to > easily pick a vector plan view from the displays. > > -----Original Message----- > From: Unidata IDV Support [mailto:address@hidden] > Sent: Tuesday, March 01, 2016 20:23 > To: Matthew Muscato <address@hidden> > Cc: address@hidden > Subject: [IDV #ZCS-923814]: Plotting Wave Directions > > Matt, > > I am still not clear on why the Derived formulas will not work for > you.
