    constantLine.AxisValue = 65.0;
    constantLine.Title.Text = "Title";    
    constantLine.RuntimeTitleEditing = true;
    constantLine.RuntimeMoving = true;

    XYDiagram diagram = chartControl1.Diagram as XYDiagram;
    diagram.AxisY.ConstantLines.Add(constantLine);

    chartControl1.ConstantLineMoved += OnChartControlConstantLineMoved;
}

private void OnChartControlConstantLineMoved(object sender, ConstantLineMovedEventArgs e) {
    e.ConstantLine.Title.Text = String.Format("{0:f3}",e.ConstantLine.AxisValue);
}
