my requirement is to enforce is a minimum height/width on each axis to ensure each "panel" doesn't become too small, but this means we might begin escaping the plot area, so we need to show scrollbars. scrollablePlotArea is only for one dimension it appears; ie I can't make it both horizontally and vertically scroll at the same time, which might happen. the scrollbar api is only applied to axes. so I thought to introduce a "fake" axis that would be the one that scrolls but I'm not sure that will accomplish what I want even if it did show up (it's not rendering in the attached sample) because it will scroll the data it's associated with and not affect the plot area for other axes. do I have to completely customize the scroll behavior to get this to work and how might I go about that?
