I would like to have support for selecting a slice of the piechart from code-behind. I have have looked into the chart and series properties but found no selectable datapoints property. The chartSelectionBehavior offers a ClearSelection method and the readonly SelectedPoints property, but nothing to add a selected point.
When you have a Chart with PieSeries and enable the SelectionBehavior - selecting a specific value makes it split from the pie chart and stand out. We should consider exposing another state, where the integrity of the pie chart is not broken and the selected items are just highlighted or probably have a bold border, etc.
In some cases, a redundant extra tick is drawn when using a DateTimeContinuousAxis.
Ability to set a custom Trackball details DataTemplate. This would allow for two scenarios: - Custom Styling - Show other values alongside data point values
Currently the labels are always positioned at the corresponding datapoint
