Can I put an upper limit on vector sizes in Ferret?
In order to see what is going on in the regions of low wind speed I have to have vector lengths that are fairly small. This causes me to get very large vectors elsewhere.
There are lots of ways to skin that particular cat.
Here's one examplewhich generates the figure above and then fixes it by plotting largewind speeds as smaller vectors in bold.
SET DATA monthly_navy_winds SET REGION/X=100w:20w/Y=80s:20s VECTOR/ASPECT/L=1/LEN=5/COLOR=BLACK uwnd,vwnd GO fland 5 VECTOR/ASPECT/L=1/LEN=5/COLOR=BLACK/OVER/NOLAB uwnd,vwnd ! ! Now the fix ! LET wspd = (uwnd^2+vwnd^2)^0.5 LET hi_threshold = if wspd gt 5 then 1 LET lo_threshold = if wspd le 5 then 1 VECTOR/ASPECT/L=1/LEN=5/title="Zonal Wind, Meridional Wind (m/s)" lo_threshold*uwnd,vwnd VECTOR/ASPECT/L=1/LEN=20/OVER/COLOR=black/THICK hi_threshold*uwnd,vwnd GO fland 5 VECTOR/ASPECT/L=1/LEN=5/OVER/COLOR=black/NOLAB lo_threshold*uwnd,vwnd VECTOR/ASPECT/L=1/LEN=20/OVER/COLOR=black/THICK/NOLAB hi_threshold*uwnd,vwnd
