Problem with the visual studio chart control in C #

Navigation
1

I'm trying to make the values that are entered in a datagridview appear in a chart of the Chart control.

I have two problems:

  • What I want is to generate for each row that I have in the datagrridview a new series that must be painted on the graph, but it paints all the data on the same line instead of the coordinates that are passed.

    • Example:

    This is the code I use: 

    for ( int i = 0; i < dataGridView1.RowCount; i++)
{   
    nom_serie = dataGridView1.Rows[i].Cells[0].Value.ToString();
    chart1.Series.Add(nom_serie);//Creamos la nueva serie
    chart1.Series[nom_serie].ChartType = SeriesChartType.Bubble;
    chart1.Series[nom_serie].XValueType = ChartValueType.Double;
    chart1.Series[nom_serie].YValueType = ChartValueType.Double;
    chart1.Series[nom_serie].Points.Add(Convert.ToDouble (dataGridView1.Rows[i].Cells[1].Value.ToString()), Convert.ToDouble (dataGridView1.Rows[i].Cells[2].Value.ToString()));

}
  • The second problem I have is that I want to be able to name the axes so they can be seen in the graph but I have not managed to get them written. I used this code: 
    •   chart1.ChartAreas[0].AxisY.Name=nomEjeY;
  chart1.ChartAreas[0].AxisX.Title=nomEjeX;
  • And finally I would like to know if there is any way that the axes could appear in the center forming a cross like the image that I show next:
