C# 窗体应用程序 Chart控件显示实时曲线

IDE: VS2019
项目模板：C# windows 窗体应用(.NET Framework)
【参考】

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。
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。
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。
在这里插入图片描述
ArtDAQ.cs代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace ArtDAQ
{public partial class ArtDAQ : Form{// 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();}x++;}}
}
