I think you'll have to use a separate graphic for this. Markers are
only shown for polygon style graphics, so you'll have to create one of
those, set its "points" property to the point where the marker should
appear and set its markerPoints property to draw whatever type of
marker you want at that point. If you only want to show the marker
when the pie slice is very small, you'll have to hide and show it at
the right times.
