Re: [ferret_users] plotting vector time series at a point

Hi Naveen,
The "ppl plotuv" command is good for this purpose though there are other ways. It works by setting up a pair of simple line plots (plot/set u,v) then using ppl plotuv to actually draw the "barbless" arrows which is what people usually want.

! demo of  barbless vector time series at a point
set view upper
def axis/t=1-jan-2009:31-dec-2009:1/units=days/t0=1-jan-2009 tax
let uwnd=randu(t[gt=tax]) ; let vwnd=randn(t[gt=tax]) plot/nolab/set uwnd,vwnd
ppl plotuv

! verify with a u,u plot that the arrows are aligned at 45deg
set view lower ; plot/nolab/set uwnd,uwnd ; ppl plotuv

Good luck,
