[yt-users] Setting limits on OffAxisProjection plots manually

[Matthew Turk]

Hi! This is a bit of a breakdown in the difference between off axis
projections and other types of plots. In general you can't pan them, if I
remember correctly, because it's a wrapper around a more expensive
operation (a type of volume rendering.) You may need to recreate it to move
the field of view.

PS don't worry about emailing the list - it's what it's here for! Glad
things are working out.
