asp.net - 在图表 ASP.NET 上将标签设置为 X 值

Question

我在 ASP.NET (.NET 3.5) 中有一个包含 3 个系列的图表。日期在代码中动态填写。如何为代码中的每个 X 条目设置标签？（标签 1、标签 2、标签 3 等）

Answer 1

也许你的意思是这个

在 aspx 中

<asp:Chart ID="Chart1" runat="server" Height="400px" Width="500px">
    <Series>
        <asp:Series Name="Series1" ChartType="Column" ChartArea="ChartArea1" />
        <asp:Series Name="Series2" ChartType="Column" ChartArea="ChartArea1" />
        <asp:Series Name="Series3" ChartType="Column" ChartArea="ChartArea1" />
    </Series>
    <ChartAreas>
        <asp:ChartArea Name="ChartArea1" />
    </ChartAreas>
</asp:Chart>

绑定数据

  protected void Page_Load(object sender, EventArgs e)
        {
            // Initialize arrays for series 1
            double[] yval1 = { 2, 6, 5 };
            string[] xval1 = { "Peter", "Andrew", "Julie" };

            // Initialize arrays for series 2
            double[] yval2 = { 4, 5, 3 };
            string[] xval2 = { "Peter", "Andrew", "Julie" };

            // Initialize arrays for series 3
            double[] yval3 = { 6, 5,7 };
            string[] xval3 = { "Peter", "Andrew", "Julie" };

            // Bind the arrays to each data series
            Chart1.Series["Series1"].Points.DataBindXY(xval1, yval1);
            Chart1.Series["Series2"].Points.DataBindXY(xval2, yval2);
            Chart1.Series["Series3"].Points.DataBindXY(xval3, yval3);

            // Align series using their X axis labels
            Chart1.AlignDataPointsByAxisLabel();

        }
