Multiple Legend Items from a single QwtPlotItem

I'm trying to extend QwtPlotItem and create a Pie Graph,
I have everything else working, but I was wondering if it's possible to display multiple legend items from a single QwtPlotItem?

Thanks.

I'm not sure if a pie chart makes much sense as it is completely unrelated to the axes scales ( that's why I never implemented such an item ), but you can use any type of widget to represent an item on the legend.
