Thanks, I now understand better what is the main goal of EllipseCollection: in
a quiver-like use, you don't want indeed the plotted ellipses to change size
and/or orientation with scaling and zooming.

Yes, in the context of error-ellipses, I would like to see my ellipses scale
with x and y, as they do when I plot them individually as Ellipse patches (see
example scripts, the blue ellipses are what I would like to obtain using an
EllipseCollection), something like "units='data'" in EllipseCollection...
Cheers,
