Hello,

You can try code similar to the following:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;


      Line line1 = new Line(tChart1.Chart);
      Line line2 = new Line(tChart1.Chart);

      tChart1.Panel.MarginLeft = 10;

      Axis axis1 = tChart1.Axes.Custom.Add();
      line1.CustomVertAxis = axis1;
      axis1.PositionUnits = PositionUnits.Pixels;
      axis1.RelativePosition = -50;

      line1.FillSampleValues();
      line2.FillSampleValues();

      tChart1.AfterDraw += TChart1_AfterDraw;

    }

    private void TChart1_AfterDraw(object sender, Graphics3D g)
    {
      int xPos = tChart1.Axes.Custom[0].Position;
      int yPos = tChart1.Axes.Custom[0].IStartPos;

      Point from = new Point(xPos, yPos - 40);
      Point to = new Point(xPos, yPos - 5);

      g.Brush.Color = Color.Green;
      g.Arrow(true, from, to, 10, 10, 0);
    }
