请注意，SalesData 类为Public类型。这是数据绑定所必需的。
在创建图表时，我们将遵循以下四个主要步骤：步骤步骤{*}1{*}）选择图表类型：）选择图表类型：
下面的代码将清除任何现有的序列，然后设置图表类型：

       ChartType = ChartType.Line,
       XValuesSource = <span style="color: #0000ff">new</span> <span style="color: #0000ff">double</span>\[\] \{ 1, 2, 3 \},
       ValuesSource = <span style="color: #0000ff">new</span> <span style="color: #0000ff">double</span>\[\] \{ 3, 2, 1 \} \});
<span style="color: #3f529c">柱形折线图</span>
使用不同的数据系列模板，很容易生成各种图表类型组合。
该图表可以通过设置DataSeries.ChartType创建。

\});         c1Chart1.ChartType = ChartType.LineSymbols;
        c1Chart1.View.AxisY.ItemsSource = <span style="color: #0000ff">new</span> <span style="color: #0000ff">double</span>\[\] \{ 1.25, 1.5, 1.75, 4 \};
