As far as I know, there isn't any way to trigger the built-in tooltip on mouseover of the legend. However, you can register event handlers for the 'mouseover' and 'mouseout' events thrown by the pie chart, which pass row and column indices for the data point in the dataTable which you can use to build your own tooltips. The mouse events are thrown by both the pie slices and the legend entries.
