You can use labelFunction in mx:PieSeries, and lableFunction look like that

private function pieSeries_labelFunc(item:Object, field:String, index:Number, percentValue:Number):String 
{
    return StringUtil.substitute("{0} ({1}%)",item.description,percentValue.toFixed(1));
}

Where description is the label that you want to see. feel free to ask any question.

Take a look at amCharts Bundle for WPF. Pie chart supports labels on the slices, outside connected labels and includes an algorithm to prevent label overlapping.

If you are looking to put labels on the chart itself (instead of tooltip), take a look at this great blog post by WPF guru Bea Stollnitz.

It shows how to do this, in many different modes, and explains not only how, but why.

I've just followed this tutorial (just to make sure) and I get the percentages of each slice as tooltip on mouse over by default.

If you post your code we might be able to spot if there's a problem with it.
