Matplotlib: 3D Arrows and 3D Annotations

PY-Drawing3D.ipynb

thanks

Good job! thank you!

I was thinking about how to solve such a 3D arrow annotation and found that you have created and perfected this feature, many thanks, sincere thanks from the other side of the internet！

Works for me. Thank you!

thanks

Awesome, thank you!

Just what I needed. Thank you!!

Thanks for the gist! Is there a license for it?

One suggestion for this code is add return arrow to the end of def _arrow3D to read:

def _arrow3D(ax, x, y, z, dx, dy, dz, *args, **kwargs):
    '''Add an 3d arrow to an `Axes3D` instance.'''

    arrow = Arrow3D(x, y, z, dx, dy, dz, *args, **kwargs)
    ax.add_artist(arrow)
    return arrow

This will make other artist3d functions work, such as set_visible

P.S. Would you like to PR to matplotlib? This would be helpful...

tested on November 12, 2023 and works

Thanks!
