Remarks

Data sources include Element, Series, and AxisMarker objects. When the source is specified, any tokens associated with the source type may be used.

Series mySeries = new Series();
mySeries.Name = "Test Series";
Annotation a = new Annotation();
a.DataSource = mySeries;
a.Label.Text = "%Name";
Chart.Annotations.Add(a);
 
// When this chart renders, the annotation will read 'Test Series'.

Visual Basic

Dim mySeries As New Series()
mySeries.Name = "Test Series"
Dim a As New Annotation()
a.DataSource = mySeries
a.Label.Text = "%Name"
Chart.Annotations.Add(a)
 
' When this chart renders, the annotation will read 'Test Series'.
