I do know this is just a practise code. But it still doesn't get close to what i needed. The above code, i can only see the mouse pointer on graph within the graph. Any mouse coordinates outside of the graph gets rejected and not shown.
If i on the Autoscale, the scale jumps crazily to a infinite number. Please help.
I will just let you know what i am accomplishing.
I am actually working on a final year project that detects the fall risk. My team has decided to use the graphical tablet to detect the movement of the patient attached with a buckle and a rod sticking out attached with a stylus at the other end of the pole. So my task now is to make as if my screen to be the XY Graph so wherever i move on the screen, the graph will show my movement on the screen with plotted lines
