Is drill downs possible on all chart types?

[eo]

Hi

I have created a similar posting before, but this one is slightly different.
I have a cross tab, and a stacked area chart based on that. I thought drill down to the (ultimately) base data is possible, but this seems to be not the case.
So my only solution was to create a chart based on normal grouping and summaries (i will still include the cross-tab only for display purposes). I can however not seem to get a drill down from the stacked area chart to the raw data right. Is this at all possible?

I am currently using CE10.

Thanks
