如何使用MSChart對角線繪製帶狀線？

Question

調整MS圖表。我已經成功繪製了一張動態圖表，但需要在圖表上繪製一條線（黃色）。我將如何繪製（黃色）線。我有X和Y值。

這裏是你可以玩一個例子：

// we create a general LineAnnotation, ie not Vertical or Horizontal: 
LineAnnotation lan = new LineAnnotation(); 

// we use Axis scaling, not chart scaling 
lan.IsSizeAlwaysRelative = false; 

lan.LineColor = Color.Yellow; 
lan.LineWidth = 5; 

// the coordinates of the starting point in axis measurement 
lan.X = 3.5d; 
lan.Y = 0d; 
// the size: 
lan.Width = -3.5d; 
lan.Height = 5.5d; 

// looks like we need an anchor point, no matter which.. 
lan.AnchorDataPoint = yourSeries.Points[0]; 

// now we can add the LineAnnotation; 
chart1.Annotations.Add(lan);
