Select objects in Runtime to create a graph

Hello,
I want to create a graph of selected objects in Runtime. For example, I have 10 different sensors in the screen. I want to select only 3 of them: one current sensor and two voltage sensors. I want to select them with mouse click + shift button and then I press special button which creates a graph (x-axis shows time, Y-axis current in amps and voltage in volts). How can I do this?
