開發需要獲取當前點擊Chart的坐標和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軸:'" + Result.Series.Points[Result.PointIndex].XValue.ToString() + <span style="font-family: Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace; white-space: nowrap;">"'Y軸:'" + Result.Series.Points[Result.PointIndex].YValues[0].ToString());</span>

 

 

Result.Series 就是點擊獲得的Series

 

Result.Series.Points[Result.PointIndex].XValue 為點擊Series X坐標

 

Result.Series.Points[Result.PointIndex].YValue 為點擊Series Y坐標
