VC2010用MFC单个文档做串口采集数据并画图的程序

Question

我先画了个表
void Cdanwen2View::Onquxian()
{
// TODO: 在此添加命令处理程序代码
CClientDC* pDC=new CClientDC(this);
// CPen * newpen =(PS_DASHDOTDOT,1,(COLORREF) 0);
// CPen* oldpen=pDC->SelectObject(&newpen);
CPen pen;
CPen * pen1=new CPen(0,1,RGB(0,0,0));//黑色
pDC->SelectObject(pen1);       // 选择画笔绘出通道的颜色标志
pDC->SetTextColor(RGB(255,0,0));  // 设定文本颜色为红色
pDC->MoveTo(40,420);
pDC->LineTo(7000,420);
pDC->MoveTo(50,430);
pDC->LineTo(50,20);
pDC->LineTo(45,25);
pDC->MoveTo(50,20);
pDC->LineTo(55,25);
pDC->MoveTo(50,100);
    pDC->LineTo(38,100);
pDC->MoveTo(50,180);
    pDC->LineTo(38,180);
pDC->MoveTo(50,260);
    pDC->LineTo(38,260);
pDC->MoveTo(50,340);
    pDC->LineTo(38,340);
pDC->TextOut(30,400,_T("0"));
pDC->TextOut(30,320,_T("10"));
pDC->TextOut(30,240,_T("20"));
pDC->TextOut(30,160,_T("30"));
pDC->TextOut(30,80,_T("40"));//画坐标
    pDC->TextOut(60,30,_T("v/m/s"));
    pDC->TextOut(1000,400,_T("t/100ms"));  // TextOut()函数在指定位置输出文本，标出横纵坐标分别代表v和t下面应该是设置串口和打开串口，得到数据的程序了，我是新手，最近在做毕设，学的都不是这，悲剧！谢谢各位了，看到了告诉我是不是这么整？
