Real-time graph in Android with OpenGL

Hello! Could you give me some sample code of real-time graph in Android(or java code)with OpenGL? Thanks in advance!

No, because this not an OpenGL ES forum. Plus, I’m pretty sure Google will offer much material on the matter and if not Google will help you find something quickly. In fact, I entered three words and got the top hit right away. You can do it! Fight the laziness!
