本示例演示了在运行时刻如何创建并定制数值带。

因为数值带位于对应轴的数值带集合中，因此首先应把图象对象转换为所需的图象类型。此后，就可以通过 Axis2D.Strips 属性来访问数值带集合。

// Cast the chart's diagram to the XYDiagram type, to access its axes. XYDiagram diagram = (XYDiagram)chartControl1.Diagram; // Create a strip with its maximum and minimum axis value defined. diagram.AxisY.Strips.Add(new Strip("Strip 1", 5, 15)); // Customize the strip's behavior. diagram.AxisY.Strips[0].Visible = true; diagram.AxisY.Strips[0].ShowAxisLabel = true; diagram.AxisY.Strips[0].AxisLabelText = "My Range"; diagram.AxisY.Strips[0].ShowInLegend = true; diagram.AxisY.Strips[0].LegendText = "A Sample Strip"; // Customize the strip's appearance. diagram.AxisY.Strips[0].Color = Color.CornflowerBlue; diagram.AxisY.Strips[0].FillStyle.FillMode = FillMode.Empty;
