本示例展示了如何为股价视图类型的系列显示回归线。

为了访问系列的指标线集合 (通过 XYDiagram2DSeriesViewBase.Indicators 属性)，应该把系列视图转换为适当的类型。

C#	复制代码
// Create a regression line for the Open value level. RegressionLine myLine = new RegressionLine(ValueLevel.Open); // Access the series collection of indicators, // and add the regression line to it. ((StockSeriesView)chartControl1.Series[0].View).Indicators.Add(myLine); // Customize the regression line's appearance. myLine.LineStyle.DashStyle = DashStyle.DashDot; myLine.LineStyle.Thickness = 2; myLine.Color = Color.Crimson;

复制代码

// Create a regression line for the Open value level.
RegressionLine myLine = new RegressionLine(ValueLevel.Open);

// Access the series collection of indicators,
// and add the regression line to it.
((StockSeriesView)chartControl1.Series[0].View).Indicators.Add(myLine);

// Customize the regression line's appearance.
myLine.LineStyle.DashStyle = DashStyle.DashDot;
myLine.LineStyle.Thickness = 2;
myLine.Color = Color.Crimson;

Visual Basic	复制代码
' Create a regression line for the Open value level. Dim myLine As New RegressionLine(ValueLevel.Open) ' Access the series collection of indicators, ' and add the regression line to it. CType(chartControl1.Series(0).View, StockSeriesView).Indicators.Add(myLine) ' Customize the regression line's appearance. myLine.LineStyle.DashStyle = DashStyle.DashDot myLine.LineStyle.Thickness = 2 myLine.Color = Color.Crimson

Visual Basic

复制代码

' Create a regression line for the Open value level.
Dim myLine As New RegressionLine(ValueLevel.Open)

' Access the series collection of indicators,
' and add the regression line to it.
CType(chartControl1.Series(0).View, StockSeriesView).Indicators.Add(myLine)

' Customize the regression line's appearance.
myLine.LineStyle.DashStyle = DashStyle.DashDot
myLine.LineStyle.Thickness = 2
myLine.Color = Color.Crimson
