I have this question to start off on my basic interface. I need 4 graphs and 4 buttons to connect. Lets say, I would want to just bring out 4 graphs and connect them to 4 different buttons. How do I go about connecting them, so that they'll overlap each other as their respective buttons are clicked. Eg. if Button 1 is clicked, the graph 1 should come out. & if Button 2 is clicked after that, graph 2 should over lap it. Thanks.
