WPF DevExpress Chart控件多Y轴，指定数据参考的Y轴

当Chart中有两个及以上的Y轴时，我们就要指明图表中的柱子或折线对应的是哪个Y轴了，这时候需要指明柱子或者折线的dxc:XYDiagram2D.SeriesAxisY属性，来设置对应的Y轴（dxc:XYDiagram2D.SeriesAxisY="{Binding ElementName=y2}"），其中Binding的ElementName就是需要对应的Y轴的Name（即这里的y2），界面代码如下：

<dxc:ChartControl  DataSource="{Binding SaleAmountAnalysisList}">  
            <dxc:XYDiagram2D x:Name="diagram1" SeriesDataMember="Gross">  
                <dxc:XYDiagram2D.SecondaryAxesY>  
                    <dxc:SecondaryAxisY2D x:Name="y2">  
                        <dxc:SecondaryAxisY2D.Title>  
                            <dxc:AxisTitle Content="单位（万）"></dxc:AxisTitle>  
                        </dxc:SecondaryAxisY2D.Title>  
                    </dxc:SecondaryAxisY2D>  
                </dxc:XYDiagram2D.SecondaryAxesY>  
                <dxc:XYDiagram2D.AxisY>  
                    <dxc:AxisY2D x:Name="firstY">  
                        <dxc:AxisY2D.Title>  
                            <dxc:AxisTitle Content="单位（千）" />  
                        </dxc:AxisY2D.Title>  
                    </dxc:AxisY2D>  
                </dxc:XYDiagram2D.AxisY>  
                <dxc:XYDiagram2D.AxisX>  
                    <dxc:AxisX2D />  
                </dxc:XYDiagram2D.AxisX>  
                <!--默认情况下都是参考的左边的Y轴-->  
                <!--销售提成-->  
                <dxc:BarSideBySideSeries2D LabelsVisibility="true" ArgumentDataMember="Name" ValueDataMember="Gross">  
                    </dxc:BarSideBySideSeries2D>  
                <!--单均毛利-->  
                <dxc:BarSideBySideSeries2D LabelsVisibility="true" ArgumentDataMember="Name" ValueDataMember="AveGross">  
                    </dxc:BarSideBySideSeries2D>  
                <!--贡献毛利润，通过设置LineSeries2D的dxc:XYDiagram2D.SeriesAxisY来指定该折线是参考右边的Y轴的-->  
                <dxc:LineSeries2D LabelsVisibility="True" dxc:XYDiagram2D.SeriesAxisY="{Binding ElementName=y2}" ArgumentDataMember="Name" ValueDataMember="Royalty">  
                    </dxc:LineSeries2D>  
            </dxc:XYDiagram2D>  
        </dxc:ChartControl>
