一个非常好用的MFC 曲线控件 在CDialog.h中定义控件 CChartCtrl m_cChartFx; 在CDialog.cpp中 绑定控件 DDX_Control(pDX, IDC_STATIC_FY, m_cChartFy); 初始化控件 CChartAxis *pAxis = NULL; pAxis = m_cChartFx.CreateStandardAxis(CChartCtrl::BottomAxis); pAxis->SetAutomatic(true); pAxis = m_cChartFx.CreateStandardAxis(CChartCtrl::LeftAxis); pAxis->SetAutomatic(true); m_cChartFx.GetTitle()->AddString(L"value_FX "); m_cChartFx.GetLeftAxis()->GetLabel()->SetText(L"单位：N"); m_cChartFx.GetBottomAxis()->GetLabel()->SetText(L"单位时间"); m_cChartFx.EnableRefresh(false); m_cChartFx.RemoveAllSeries();//先清空 pLineSerie1Fx = m_cChartFx.CreateLineSerie(); //创建一个曲线 m_cChartFx.EnableRefresh(true); m_cChartFx.SetBackColor(RGB(200, 200, 200)); pLineSerie1Fx->AddPoints(x, theApp.m_SaveDataFy, theApp.m_index); //画数据点
