MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

for PSCAD softwear it can be very easy and coming soon challenger in this soft
