Hi all, I try to plot data spaced approximately 5km. I use res@vcMinDistanceF to choose density of my vectors, but I feel that this does not represent the good spacing between each grid point : 1 vector each 10km instead of 5km, even if I don't use vcMinDistanceF ressource .   here's elements from my script ;where vectors should lie on the map :   res@sfXCStartV = min(wind&lon)   res@sfXCEndV   = max(wind&lon)    res@sfYCStartV = min(wind&lat)   res@sfYCEndV   = max(wind&lat)   res@mpLimitMode = "latlon"                           ;define map's corners   res@mpMinLonF             =  minlon   res@mpMaxLonF             = maxlon   res@mpMinLatF             =  minlat   res@mpMaxLatF             =  maxlat ;vc ressources : res = True res@vcGlyphStyle                    = "LineArrow"      ; vectorstyle res@vcRefLengthF                   = 0.01               ; ref vec length ;lres@vcMinDistanceF               = 0.014                 ; larger means sparser res@vcVectorDrawOrder         = "PreDraw"        ; draw order res@vcMonoLineArrowColor  = True                   ; vector in black Thanks in advance. Yann
