DataPoints

Gets the collection of data points associated with the series.

Declaration
public ElementCollection<PieDataPoint> DataPoints { get; }
Property Value
ElementCollection<PieDataPoint>

DefaultSliceStyle

Methods

GetLabelConnector(ChartSeriesLabelPositionInfo)

Gets the points which build the label connector polyline.

Declaration
protected override List<Point> GetLabelConnector(ChartSeriesLabelPositionInfo info)
Parameters
ChartSeriesLabelPositionInfo info

Returns
System.Collections.Generic.List<System.Windows.Point>

Overrides

GetValueAggregateFunction()

When overridden in a derived class, this method returns the function used to calculate the aggregate values for the Value property.

Declaration
protected virtual ChartAggregateFunction GetValueAggregateFunction()
Returns
ChartAggregateFunction

OnApplyTemplate()

When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call System.Windows.Controls.Control.ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in an application. For more information, see Remarks.

Declaration
public override void OnApplyTemplate()
Overrides

OnAttached()

Occurs when the presenter has been successfully attached to its owning RadChartBase instance.

Declaration
protected override void OnAttached()
Overrides

OnCreateAutomationPeer()

Returns class-specific System.Windows.Automation.Peers.AutomationPeer implementations for the Windows Presentation Foundation (WPF) infrastructure.

Declaration
protected override AutomationPeer OnCreateAutomationPeer()
Returns
System.Windows.Automation.Peers.AutomationPeer

The type-specific System.Windows.Automation.Peers.AutomationPeer implementation.

OnLoaded(Object, RoutedEventArgs)

Occurs when a System.Windows.FrameworkElement has been constructed and added to the object tree.

Declaration
protected override void OnLoaded(object sender, RoutedEventArgs e)
Parameters
System.Object sender

System.Windows.RoutedEventArgs e

Overrides

OnMouseLeave(MouseEventArgs)

Invoked when an unhandled System.Windows.Input.Mouse.MouseLeave attached event is raised on this element. Implement this method to add class handling for this event.

Declaration
protected override void OnMouseLeave(MouseEventArgs e)
Parameters
System.Windows.Input.MouseEventArgs e

The System.Windows.Input.MouseEventArgs that contains the event data.

OnMouseMove(MouseEventArgs)

Invoked when an unhandled System.Windows.Input.Mouse.MouseMove attached event reaches an element in its route that is derived from this class. Implement this method to add class handling for this event.

Declaration
protected override void OnMouseMove(MouseEventArgs e)
Parameters
System.Windows.Input.MouseEventArgs e

The System.Windows.Input.MouseEventArgs that contains the event data.

OnPlayPointAnimations(Boolean)

Fired when Point animations are about to be played.

Declaration
protected override void OnPlayPointAnimations(bool hidePointsOnLoad)
Parameters
System.Boolean hidePointsOnLoad

When true, the animated element is collapsed until the start of the animation.
