Markers are symbols used to identify the individual data values i.e. the point of intersection of an X and Y coordinate on a chart. Markers can only be used with Area, Line and XYScatter charts. The following symbols can be used as markers:

The following code shows how to add marker to the series in a line chart:

DateTimeLineSeries lineSeries = new DateTimeLineSeries("Series name");
Marker marker = Marker.GetCircle(2);
lineSeries.Marker = marker;       
Dim MyLineSeries As DateTimeLineSeries = New DateTimeLineSeries("Series name")
Dim MyMarker As Marker = Marker.GetCircle(2)
MyLineSeries.Marker = MyMarker  

Note: Markers can also be added from the series constructors.
