If you take a look on the attached screenshot (which is from the sample gallary)
In this stacked chart there are 3 datasets(2004,2005,2006) - after the user has choosen to hide the 2005 dataset, 2006 hangs "floating" above the 2004 data.
What i'm asking is whether it is possible to apply some form of "gravity" so the 2006 falls down ontop of 2004 and thus removing the gap?
