msChart控件 柱状图 Y主轴Y副轴

经常遇见数据统计图，要求有Y副轴，统计图如下：

MSCHART源代码

 <asp:Chart ID="Chart1" runat="server" Width="700px" Height="300px">
            <Series>
                <asp:Series Name="Series1" ChartType="Column" BorderWidth="1" ShadowOffset="1" IsValueShownAsLabel="true"
                    IsVisibleInLegend="true" MarkerStyle="Circle">
                </asp:Series>
                <asp:Series Name="Series2" ChartType="Column" BorderWidth="1" ShadowOffset="1" IsValueShownAsLabel="true"
                    IsVisibleInLegend="false">
                </asp:Series>
            </Series>
            <ChartAreas>
                <asp:ChartArea Name="ChartArea1">
                    <AxisY LineColor="64,64,64,64" IsLabelAutoFit="false">
                        <LabelStyle />
                        <MajorGrid LineColor="64,64,64,64" />
                    </AxisY>
                    <AxisY2 LineColor="64,64,64,64" IsLabelAutoFit="false">
                        <LabelStyle />
                        <MajorGrid LineColor="64,64,64,64" />
                    </AxisY2>
                </asp:ChartArea>
            </ChartAreas>
        </asp:Chart>

后台代码：

 this.Chart1.DataSource = dt;
        this.Chart1.Series[0].YAxisType = System.Web.UI.DataVisualization.Charting.AxisType.Primary;
        this.Chart1.Series[0].XAxisType = System.Web.UI.DataVisualization.Charting.AxisType.Primary;
        this.Chart1.Series[0].XValueMember = "supplyname";
        this.Chart1.Series[0].YValueMembers = "cgsumprice";
        this.Chart1.Series[0]["PointWidth"] = "0.2";
        this.Chart1.Series[1]["PointWidth"] = "0.2";
        this.Chart1.Series[0]["DrawingStyle"] = "Cylinder";
        this.Chart1.Series[1]["DrawingStyle"] = "Cylinder";
        this.Chart1.ChartAreas[0].AxisY.Title = "采购金额(元)";
        this.Chart1.ChartAreas[0].AxisY2.Title = "交易次数(次)";
        this.Chart1.Series[1].XAxisType = System.Web.UI.DataVisualization.Charting.AxisType.Primary;
        this.Chart1.Series[1].YAxisType = System.Web.UI.DataVisualization.Charting.AxisType.Secondary;
        this.Chart1.Series[1].YValueMembers = "jylcount";
        this.Chart1.DataBind();
