In my chart class (derived from ChartView)
private void InitializeChart()
{
 CartesianCoordinates coord = new CartesianCoordinates(0, 0, 10, 10);
 LinearAxis xAxis = new LinearAxis(coord, ChartObj.X_AXIS);
 LinearAxis yAxis = new LinearAxis(coord, ChartObj.Y_AXIS);
 NumericAxisLabels yAxisLabels = new NumericAxisLabels(yAxis);
 Font font = new Font("Microsoft Sans Serif", 7);
 AxisTitle yAxisTitle = new AxisTitle(yAxis, font, "AxisTitle");
 SelectObj selectObj = new SelectObj(this);

 xAxis.CalcAutoAxis();
 yAxis.CalcAutoAxis();
 AddChartObject(xAxis);
 AddChartObject(yAxis);
 AddChartObject(yAxisLabels);
 AddChartObject(yAxisTitle);

 SetCurrentMouseListener(new SelectObj(this));
}

The SelectObj class looks like this:
public class SelectObj : FindObj
{
 public SelectObj(ExampleGraph component)
      : base(component)
 {
 }

 public override void OnMouseDown(MouseEventArgs mouseevent)
 {
   GraphObj currentObj;

   this.SetClassToFind("AxisTitle");
   base.OnMouseDown(mouseevent);
   currentObj = this.GetSelectedObject();
   if (currentObj != null)
     ((AxisTitle)currentObj).SetTextBoxMode(true);
   else
     ((AxisTitle)currentObj).SetTextBoxMode(false);

   this.GetChartObjComponent().UpdateDraw();
 }
}
