If there are multiple graphs, strange things happen. Usually one graph sits on top of the other so you can't see both, but you can see the vertical axis on the one underneath. And sometimes, when it does put them in a column, the first one is adjacent to the animation. It shows coordinate axes, it show coordinates when you move the cursor over what should be the plot area, except there is no plot area and no graph.
I thought about giving some links to programs but since they wre written by students, I suspect that would be a FERPA violation. I attached some screenshots to show what I'm talking about.
In principle, it doesn't matter since I am retiring at the end of May. But I'm still curious.
On the bright side, it seems the animations now work on Linux. No more blank, black rectangles.
