[Matplotlib-users] Wind barbs with small arrow heads

[Jesper L. <jes...@gm...>]

Hi matplotlib users

I am developing an application for showing weather forecasts using
matplotlib. We use wind barbs for displaying wind forecasts:

http://api.fcoo.dk/ifm-maps/greenland/?zoom=6&lat=62&lon=-45&layer=FCOO%20Standard&overlays=TTFFFFFFFFFFFFFFF

This is fine for our "power users". We do however also have some users who
are not used to wind barbs. I have elsewhere seen people put a small arrow
head at the foot of the wind barbs to make it more clear which direction
the wind blows toward.

As far as I can see from the matplotlib quiver.py code this is not possible
with matplotlib. But the _make_barbs method does not seem that complicated
so I wondered if it is something that I can do myself. I have however never
used the matplotlib low level drawing primitives. I would therefore
appreciate any good advice.

Best regards,
