如何在ASP.NET图表的同一轴上显示两组数据

using System;
using System.Web.UI.DataVisualization.Charting;

namespace WebApplication1
{
    public partial class ChartPage : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            // 创建数据系列
            Series series1 = new Series("Series1");
            Series series2 = new Series("Series2");

            // 设置数据系列的类型
            series1.ChartType = SeriesChartType.Line;
            series2.ChartType = SeriesChartType.Line;

            // 添加数据点到数据系列
            series1.Points.AddXY(1, 10);
            series1.Points.AddXY(2, 20);
            series1.Points.AddXY(3, 15);

            series2.Points.AddXY(1, 5);
            series2.Points.AddXY(2, 15);
            series2.Points.AddXY(3, 25);

            // 将数据系列添加到图表控件的Series集合中
            Chart1.Series.Add(series1);
            Chart1.Series.Add(series2);

            // 设置图表控件的标题和轴标题
            Chart1.Titles.Add("Chart Title");
            Chart1.ChartAreas[0].AxisX.Title = "X Axis";
            Chart1.ChartAreas[0].AxisY.Title = "Y Axis";

            // 设置图表控件的外观样式
            Chart1.BackColor = System.Drawing.Color.White;
            Chart1.BorderlineColor = System.Drawing.Color.Gray;
            Chart1.BorderlineDashStyle = ChartDashStyle.Solid;

            // 绑定数据并绘制图表
            Chart1.DataBind();
            Chart1.Visible = true;
        }
    }
}
