xlStockVOHLC chart with extra xlColumnClustered series
 

hi all,
I have ActiveChart.ChartType = xlStockVOHLC
I'm trying to add to him additional bar:
ActiveChart.SeriesCollection(6).ChartType = xlColumnClustered
and getting error "Some Charts types cannot be combined with other chart
types".
this worked for me in Office2003.
Is it possible there is no backward computability?
How can I do it in Office2007?
