Ghost scrollbar area is visible with 2-4 charts

[mikesall]

When a mouse is connected and there are 2-4 charts, the charts are first rendered with a scroll bar existing, and then the scroll bar goes away. The result is a space on right hand side where the scroll bar was.

I think there is probably a broader solution of refactoring how charts are presented, so that the PageController first figures out how all the charts should be displayed before rendering any of them.
