Attaching the Chart Label by Data Coordinate

To attach a ChartLabel to a data coordinate on the chart, set the AttachMethod property to AttachMethodEnum.DataCoordinate, and then under the AttachMethodData object set the X and Y properties to the data coordinates at which the ChartLabel is to be attached. For example, the following attaches a ChartLabel to the data coordinate (1.1, 15.8):

· Visual Basic

With C1Chart1.ChartLabels.LabelsCollection(0)

.AttachMethod = AttachMethodEnum.DataCoordinate

.AttachMethodData.X = 1.1

.AttachMethodData.Y = 15.8

End With

· C#

C1.Win.C1Chart.Label lab = C1Chart1.ChartLabels.LabelsCollection[0];

lab.AttachMethod = AttachMethodEnum.DataCoordinate;

lab.AttachMethodData.X = 1.1;

lab.AttachMethodData.Y = 15.8;

· Delphi

var

lab: C1.Win.C1Chart1.Label;

begin

lab := C1Chart1.ChartLabels.LabelsCollection[0];

lab.AttachMethod := AttachMethodEnum.DataCoordinate;

lab.AttachMethodData.X := 1.1;

lab.AttachMethodData.Y := 15.8;

end;

ChartLabels can only be attached to a data coordinate if the chart is an Area or XY-Plot. Any part of the ChartLabel that falls outside of the ChartArea is clipped.
