Method Chart.HitTest to help you.

Defines a chart element, if any, located at a point that is defined by given X and Y coordinates. For more details, refer to the official documentation at the link above.

Well, for demonstration, here's a handler that returns the Y value of the point to which it was clicked.

private void chart1_MouseClick(object sender, MouseEventArgs e) { var res = chart1.HitTest(eX, eY); if(res.Series != null) MessageBox.Show(res.Series.Points[res.PointIndex].YValues[0].ToString()); }

    Event MouseClick eX property
