I began creating an example for you and unfortunately discovered another bug further down the chain that had to do with stacking the columns. Rather than diagnose that now, here's a great blog article I found a while back that may be a better starting point, particularly since you'll get past the other annoying flex bug that messes with the visual spacing between columns when combining lines and columns. http://flexxxed.wordpress.com/2009/05/20/using-right-chart-when-you-have\ -multiple-chart-series/ <http://flexxxed.wordpress.com/2009/05/20/using-right-chart-when-you-hav\ e-multiple-chart-series/> And just an FYI - I've run into so many bugs changing from clustered to stacked to 100% at runtime that I ultimately chose to simply have multiple charts, one of each type, that I hide/show as needed. It's a headache, but since the bugs I've logged in the Adobe bug base haven't yet been addressed, it's the best solution for us. You may be luckier depending on your needs. -Eddie B.http://www.edberman.com <www.edberman.com> ---

It fails in applySeriesSet( ) in ColumnChart. as.
