BasePointMarker Class

A base class for Bitmap-rendered Point-Markers, which are small markers drawn once per data-point on a BaseRenderableSeries

Object Model

Syntax

[DefaultProperty("Content")]
[ContentProperty("Content")]
[Localizability(LocalizationCategory.None, Readability=Readability.Unreadable)]
[StyleTypedProperty(Property="FocusVisualStyle", StyleTargetType=System.Windows.Controls.Control)]
[XmlLangProperty("Language")]
[UsableDuringInitialization(true)]
[RuntimeNameProperty("Name")]
[UidProperty("Uid")]
[TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
public abstract class BasePointMarker : System.Windows.Controls.ContentControl, IPointMarker

Remarks

BasePointMarker derived types use fast bitmap rendering to draw data-points to the screen. This means that traditional WPF style tooltips won't work. For that we need to use the HitTest API. Please see the HitTest sections of the user manual for more information

Example

Shows how to create a derived class of BasePointMarker to render a custom pointmarker

public class CustomPointMarker : BasePointMarker
{
    public override void Draw(IRenderContext2D context, IEnumerable<Point> centers)
    {
        // TODO: Render a single point marker using IRenderContext2D
    }
}
