Title: Inital fix to single-series axis legend toggling bug in multiChart model

Issue seems to be with the fact that when an axis has only one series associated with it, the array of data is empty once the disabled one is filtered out.

I made a very quick fix that only filters when the data is bound to the selection, so that any series even disabled ones are included in the initial data arrays.
