Hi,
In fact, the /LENGTH qualifier can be applied to VECTOR/FLOW.
Taking the example from the Users Guide,
Here, the vector scale is listed on the plot as 2 m/s:
yes? USE coads_climatology
yes? SET REGION/x=150e:130w/y=40s:50n/l=6
yes? FLOW/ASPECT/DENSITY=4 uwnd,vwnd
Now, add a /LENGTH qualifier:
yes? FLOW/ASPECT/DENSITY=4/length=10 uwnd,vwnd
which lists the arrow scale as 5.0. (I believe that the factor of 2
involved here comes from the Vector command which draws vectors of
1/2 inch for the length requested.)

Dear Ferreters,
I am using the /flowline argument from the vector command to plot
continuous flowlines from u,v vectors. I have something like :
vector/flow/aspect=1/col=black/density=1 u,v
From the online-documentation I understood that the size of arrows
"indicate the speed of the flow".
As I am making plots for different time steps, I would like to set
manually the size of arrows, not to have it changing from one plot
to another. In other words, I am looking for a "/length="
equivalent.
Is it possible ?
Thanks,
Pierre
