I am working on a pie chart which supports drill-downs. The
idea is that when a user clicks on a chart sector a column chart is
shown on top of the pie chart showing further distribution of
values in the selected sector.
My question is what is the right way to implement this kind
of pie chart supporting drill-downs?
Should I define both charts in MXML and then dynamically make
one invisible and the other one visible? How do I swap the charts?
Any sample code will be greatly appreciated.
