ZedGraph TextLabels: align text labels on yaxis with data of y2axis (double)

Question

I'm using ZedGraph to plot data. ZedGraph is awesome for ploting many curve with good performance, but takes some time to figure out the tricks. I make many research on the net but i didn't find any solution on textlabels y axis I have a Y2axis type linear where i plot my curve, and i haveYaxis type= text where i want to show textlabel but i want that textlabel[index] is aligned with y2[index] value. To better understand, I read data from a database in this format: ----Col1------ Col2 --------Col3

----A ----------122.3 -------05:22:00

----B---------- 150.3 -------06:33:22

I try to edit the scale.majorStep, scale.min, or ScaleFormatEvent but I can not to align textlabel Yaxis with data Y2axis, beacuse y2 axis point are variable. here is the code

chart2.GraphPane.CurveList["curve1"].AddPoint((XDate)(Col3[i]), Col2[i]);
myPane02m.Y2Axis.Type = ZedGraph.AxisType.Linear;
myPane02m.YAxis.Type = ZedGraph.AxisType.Text
myPane02m.YAxis.Scale.TextLabels = Col1;
myPane02m.YAxis.Scale.Min = minY;
myPane02m.YAxis.Scale.Max = maxY;
myPane02m.Y2Axis.Scale.Min = minY;
myPane02m.Y2Axis.Scale.Max = maxY;
myPane02m.YAxis.Scale.MajorStep = Offset;
myPane02m.YAxis.Scale.MinorStep = Offset;
myPane02m.Y2Axis.Scale.MajorStep = Offset;
myPane02m.Y2Axis.Scale.MinorStep = Offset;
public string MyCustomFormatter(GraphPane pane, Axis axis, double val, int index)
{
if (index < numberPoint)
{

            string label =  getCol1().ElementAt(index).ToString();
            //MessageBox.Show(label);
            return label;
            //}
        }
        else
        {
            return "";
        }
    }

`

i want that the textlabel(Column1) is at y Axis and Col2 at y2 axis

It would be awsome if someone found a solution for my problem thanks

there's one solutioon:

Is to use Textobj and to put X=0

 double label1Y = Curve.Points[i].Y; //LineItem
    TextObj txtObj1 = new TextObj(Column1.ToString() + "   " + label1Y.ToString("0.0"), 0, label1Y, ZedGraph.CoordType.XChartFractionYScale, ZedGraph.AlignH.Right, ZedGraph.AlignV.Center);

                        txtObj1.FontSpec.Border.IsVisible = false;
                        txtObj1.FontSpec.Fill.IsVisible = false;
                        txtObj1.FontSpec.Size = 5f;
                        txtObj1.FontSpec.IsAntiAlias = true;
                        txtObj1.FontSpec.Angle = 0;
                        // MessageBox.Show(txtObj1.FontSpec.StringAlignment.ToString());
                        txtObj1.IsVisible = true;
                        //txtObj1.Location.
                        txtObj1.ZOrder = ZOrder.A_InFront;

                        //txtObj1.IsInFrontOfData(true);
                        chart2.GraphPane.GraphObjList.Add(txtObj1);
