How to apply a bevel filter for each slice of a flex 4 pie chart?

Onl开发者_Python百科y succeeded with applying it around the whole pie chart.

I achieved this finally by applying the filter to each slice and slightly increasing the distanc between the wedges.

series.explodeRadius=0.01;

series.filters = [bevel];

Convert the segment of chart into a symbol and apply the filter to that on it's own?
