[yt-users] velocity vectors on a projection

[Andrew Myers]

Hi Mike,

I think that annotate_velocity should work for axis-aligned slices and
projections. If you're doing off-axis, then the velocity and magnetic field
callbacks don't work out of the box (last time I checked anyway), but it's
still possible to use yt to compute the velocity vectors and manually add
them to your projection via matplotlib's quiver command.
Here<http://paste.yt-project.org/show/4272/>is a script I wrote that
does this for the magnetic field. In the image it
produces, the colorscale shows the density-weighted temperature projection
and the arrows show the density-weighted mean magnetic field vectors.

Hope this helps,
Andrew
