【参考】

1. B站上教程C#Chart控件画折线图的使用，关于Chart控件的属性，介绍得非常详细。
2. B站上教程C#上位机Chart控件实时曲线终极讲解，对鼠标滚轮事件等，多个事件的讲解较为详细。
3. 工具箱中找不到Chart控件怎么办->VS/C#添加chart控件
   项目结构非常简单，一个窗体ArtDAQ.cs和一个主程序Program
   # 【遇到的问题】
   Timer控件拖拽到设计器上，显示不出来，无法通过双击的方式给Timer控件添加事件
   手动写了一个InitializeTimer函数，在该函数中，给Timer控件的对象timer1绑定了一个事件timer1_Tick

timer1.Tick += new EventHandler(timer1_Tick);

把InitializeTimer函数添加进ArtDAQ的构造函数中，然后在后面继续写timer1_Tick函数。

        // 设置Tiemr事件的间隔事件
        private void InitializeTimer()
        {
            // 设置Timer事件的间隔时间（在此例中为2000毫秒）
            timer1.Interval = 100;
            // 启动Timer
            // timer1.Start();
            // 绑定Tick事件
            timer1.Tick += new EventHandler(timer1_Tick);
        }

        // 构造函数
        public ArtDAQ()
        {
            InitializeComponent();
            InitializeTimer();
        }
        
        // 触发按钮
        private void button1_Click(object sender, EventArgs e)
        {
           if (timer1.Enabled == false)
            {
                // timer1.Enabled = true;
                timer1.Start();
                MessageBox.Show(timer1.Enabled.ToString());
            }
           else
            {
                timer1.Enabled = false;
            }
        }

        // Timer的事件
        // 随机数
        Random rd = new Random();       
        int x = 0;
        int y = 0;

        private void timer1_Tick(object sender, EventArgs e)
        {
            y = rd.Next(0, 100+1);
            chart1.Series[0].Points.AddXY(x, y);
            if(x>=101)
            {
                timer1.Enabled = false;
                // timer1.Stop();
            }
