[yt-users] line annotations, center and zooming

[David Collins]

Hi again--

Sorry, my last email didn't actually have a question in it.

Does anyone know how to get the coordinates that the plot window uses
(after re-centering and zooming) and the coordinates of the
annotate_image_line to agree?

Thanks,
d.
