How do I plot a continuous sine or cosine wave on a Dot marix LCD using C++? Can I have a sample to see? Thank in advance..

I do not understand what type of application do you want to create. Is it console or window application. In the second case, you can use qwt library.

You would have to develop an algorithm that would actually grab data points from what ever your input is, and then use a graphical library to loop through and draw each point on a window.

What are you trying to grab data points from?
