hi
Ok, your installation is not unusual. I was wondering if was our Mac
version and something funny had happened in that build.
Could you send me your data? NetCDF files attach to emails just
fine. Perhaps put all the variables in one file with a Ferret
SAVE/APPEND, and if any of the variables have more than one timestep
or depth, just send one T and Z. I'm curious to see if I can find
out what's happening.
My example is here and you can see the arrow heads are similar with
or without the curvilinear version of the vector command.

Hi -
I don't know what is happening here either. I do not see
this kind of thing with various examples I have that use
curvilinear coordinate grids. What version of Ferret are you
running, and on which operating system?

hello Ansley,
I tried as You advised me but still with no success.
The vector plot command is like this:
vector/over/title="WIND"/length=5/xskip=18/yskip=18
wlon[d=1], wlat[d=2],lon[d=3],lat[d=4]
I don't have any idea how to work around that issue.
Many thanks!
p.s.
I attach a graphic file.

Hi Szymon,
I think that the arrow heads are being drawn but
are too small. The algorithm makes a choice on
the length scale for the vectors and that
includes the size of the arrow heads, but for this
case the default scale isn't a good one. In your
example, the length scale that's used is 20. Try
your curvilinear plot with a smaller value, say
VECTOR/LENGTH=10, or VECTOR/LENGTH=5
I've attached an example I tried, where the plot
that used a setting of /LENGTH=1 had very small
arrow heads, and /LENGTH=0.5 draws larger ones.

Hi there,
It's an odd issue when I draw vectors (wind
data) on curvilinear grid the arrow-heads
are missing.
Everything is correct when I draw in
rectilinear coordinates.
I attach files.
