开发需要获取当前点击Chart的坐标和Series 的Name，label，找了半天才找到啊

在Click或者Mouse的click事件中添加

 

1.  
   System.Windows.Forms.DataVisualization.Charting.HitTestResult Result = new System.Windows.Forms.DataVisualization.Charting.HitTestResult();
2.  
   Result = chart1.HitTest(e.X, e.Y);
3.  
   if(Result.Series!=null)
4.  
   MessageBox.Show("'X轴:'" + Result.Series.Points[Result.PointIndex].XValue.ToString() + <span style="font-family: Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace; white-space: nowrap;">"'Y轴:'" + Result.Series.Points[Result.PointIndex].YValues[0].ToString());</span>

 

 

Result.Series 就是点击获得的Series

 

Result.Series.Points[Result.PointIndex].XValue 为点击Series X坐标

 

Result.Series.Points[Result.PointIndex].YValue 为点击Series Y坐标
