This is essentially the same question as you posted here[^]. If you do not understand the basics of reading information from a file and plotting points, drawing lines, on an output device then you need to go back to your study guides and programming tutorials and spend some time getting familiar with these aspects of development.

Try a bit of research for yourself, it really is not that difficult.

If you actually made an effort to do some study for yourself and came back with specific questions then people would be more than willing to help you. But you are asking for a complete solution without being prepared to even try to learn the subject for yourself. I already suggested that you should try your study guides, maybe learn how to read data from a file and construct an array of points, which will then allow you to draw some lines on your output device. The CFile class will help you read the data, and the Windows GDI or GDI+ functions will help you draw the lines.

Perhaps a change of attitude will get you better answers in the future.

Read the data in the opposite way you have written them into arrays (type of arrays depends on the used visualization implementation).

There are many articles here on CodeProject about graphical visualization of 2D data. Use the search function[^].

One of my favorites is the High-speed Charting Control[^].
