i need to plot a graph and have no idea how to even kick start. These is what how dynamic the graph is:
Basically is letting user trace the point(the correct X and Y coordination) on the graph and allow them to plot the graph. For example, when the user click on the correct coordination, a dot will appear and when the user click on the 2nd coordination, a line will appear to connect the first point to the 2nd one and etc. The last fucntion of this graph is to have a clear button that allow the user to clear the last plot attempt and so forth so that the user can continue to plot the graph.
Any idea where can i get the necessary information and possible someone can offer me some advice ?
