如何使用ZedGraph库显示具有通用X轴的多个图形？

using System;
using System.Windows.Forms;
using ZedGraph;

namespace ZedGraphDemo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            // 创建一个GraphPane对象
            GraphPane graphPane = zedGraphControl1.GraphPane;

            // 设置X轴标签
            graphPane.XAxis.Title.Text = "X轴标签";

            // 创建第一个图形
            LineItem lineItem1 = graphPane.AddCurve("曲线1", GenerateData(1), Color.Red, SymbolType.None);
            lineItem1.Line.Width = 2;

            // 创建第二个图形
            LineItem lineItem2 = graphPane.AddCurve("曲线2", GenerateData(2), Color.Blue, SymbolType.None);
            lineItem2.Line.Width = 2;

            // 刷新图表
            zedGraphControl1.Refresh();
        }

        private PointPairList GenerateData(double offset)
        {
            PointPairList pointPairList = new PointPairList();

            for (double x = 0; x < 10; x += 0.1)
            {
                double y = Math.Sin(x + offset);
                pointPairList.Add(x, y);
            }

            return pointPairList;
        }
    }
}
