Pie slice transparency

Can a pie slice have transparency? If so, how?

Thanks

Thanks for the response.

I'll explain what I am doing, maybe there is a different solution (I don't see one--but I've seen a lot of creative solutions here).

I have a number of TBarSeries that are stacked--each stack representing a year. A bar can have series that has it's transparency value set to something other than zero. The user can click on a stacked bar series, which will give them a pie chart showing the details of the year. The problem is that the stacked bar series that has it's transparency set will have a different appearance than the pie slice. I've got the legend working fine--so it is correct.

My guess is that I have to wait for the transparent pie slice, correct?

Hi Ed Dressel,

Does the bars transparency represent anything specific? If not, maybe you could force the clicked stacked bar not to be transparent (as it the selected one) so that neither the stacked bar nor its pie will have transparency. And you could restore the stacked bar transparency when the pie is hided.

It's a user configuration and represents a shortfall (that's why a transparent appearance is great for this--it appears empty).

I think I could wash the color with white (60% transparency means 60% of white with 40% of the user selected color).

It will be nice when this is fixed.
