如何在运行c#winforms应用程序时在图表中显示默认的虚拟数据集

我想知道在应用程序运行后,是否可以让图表显示其默认数据集,而不是空白页。

在visual studio中创建图表时,它会显示一些默认数据:

但是,当应用程序运行时,生成的图表为空:

作为一种替代解决方案,我可以创建自己的默认虚拟数据,如下所示: c# chart axis not displaying when form is loaded .

代码示例和空白图表(需要引用System.Windows.Forms.DataVisualization):

using System;
using System.Windows.Forms;

namespace ChartExample
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Chart());
        }
    }

    public class Chart: Form
    {
        /// <summary>

        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
