Visual Basic 6 Graphing Calculator

Hello,

I have a computer science asssignment that requires me to create a graphing calculator. I have the code for the arithmetic but I need to know how to create a graph to plot XY coordinates. The program must output the XY coordinates from -10 to 10 as well as graph the line/curve. Could anybody help me with creating or adding some way to output a graph and the coordinates?

Thanks.
