Plot disappears in interactive
I made an interactive as an exercise for my students. They have to look at a plot and answer two questions using pull-down menus. To prevent gratuitous reloading (and possibly other problems), I made auto_update false. The problem is that when you pick an option in one menu, the plot disappears. This doesn't happen on the Sage cell server. Is there any way I can get it to stop happening in a regular worksheet?
The sage cell interact is a different codebase... that is a good feature. The upcoming Salvus/sagemathcloud/whatever also has a different implementation.
So you might just have to wait until that gets into Sage proper...
