环境：VS2017 + TeeChart5
由于毕设被迫需要使用MFC来设计程序（这显然是个很糟糕的选择），在安装与使用TeeChart插件时出现了许多问题。在2023年间我们尝试去使用1992年的技术时出现了各问题，而且这些技术正在被逐渐淘汰，相关的技术文章也并不充分。[MFC]系列将用于记录我毕设期间所遇到的难点问题，向这一古老且经典的技术示以崇高的敬意！
1-1 安装TeeChart
解压TeeChart.Pro.v5.ActiveX.7z文件，打开安装程序，使用sn.txt中的License和Password
默认安装位置C:\Program Files (x86)\TeeChart Pro v5 ActiveX Control
其余步骤按提示进行。
安装完成之后在windows搜索输入cmd，选择以管理员方式打开。
依次输入(文件路径为TeeChart安装路径)
cd C:\Program Files (x86)\TeeChart Pro v5 ActiveX Control
regsvr32 TeeChart5.ocx
当出现如下提示即为安装成功
1-2 在VS中插入控件
打开VS2017 -> 新建MFC项目 -> 选择基于对话框 -> 完成
在标题栏点击工具 -> 选择工具箱
在COM组件中选择TeeChart Pro Activex Control v5
在工具箱中添加TeeChart Pro Activex control v5和一个按钮，并适当调整位置大小
1-3 添加类与变量
右击项目名称 -> 类向导
选择添加类型库中的MFC类
可用类型库选择TeeChart Pro Activex Control v5<1.0>，在接口中选择ISeries和ITChart。点击完成后头文件中会生成CSeries.h和CTChart.h两个头文件。
分别打开这两个头文件并分别对其中的第三行代码添加//，将其注释掉
//#import "C:\\WINDOWS\\SysWow64\\TeeChart5.ocx" no_namespace
右击插入的TeeChart控件，选择添加变量
名称输入为m_chart，变量类型为CTChart1。点击完成之后头文件中新生成了一个COCX.h的头文件
然而这个COCX.h文件并不完整，我们需要在其中插入一些方法，代码如下

1-4 设置图表
双击插入的TeeChart控件，点击ADD，选择fastline，取消勾选3D
双击添加的Button控件，进入OnBnClickedButton1()函数。在为该函数添加语句之前先为该文件添加两个头文件
#include "CSeries.h"
#include "CTChart.h"
然后在OnBnClickedButton1()函数中输入以下内容
void CChartDemoDlg::OnBnClickedButton1()
{
// TODO: 在此添加控件通知处理程序代码
CSeries lineSeries = (CSeries)m_chart.Series(0);
lineSeries.Clear();
for (int i = 0; i < 50; i++)
lineSeries.AddXY((double)i, rand(), NULL, NULL);
}
最后就可以运行本地Windows调试器，点击Button1按钮得到下面实例结果
