The trackball doesn't provide a property that controls its visibility. The most convenient approach to enable or disable it would be to add/remove it from the Behaviors collection of the chart control. An alternative approach would be to set the Position property of the trackball behavior to new Point(double.NaN, double.NaN). However, using this option you will need to manually set the Position on each MouseMove. Otherwise, the chart will override its value when you mouse over the chart.
