如何使用MSChart对角绘制带状线？

Question

调整MS图表。我已成功绘制动态图表但需要在图表上绘制一条线（黄色）。我将如何画（黄色）线。我有X和Y值。

Answer 1

以下是您可以使用的示例：

// 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);
