by clicking on the graph of a particular device in one mashup should open that in new mashup

I have one requirement, when I selected the device on the list in one mashup it shows the graph on that mashup, if I click on that graph that same graph of that particular device should open in new mashup with selected device also, after opening the graph i need to add some more functionality on that. when I click on the graph it is not showing that particular graph with selected device on the list.

how could I map the selected device name on the list in one mashup and in other mashup. when I selected teh device from the list that same device should select in another mashup when I navigate to that mashup.

can I bind more than one service to the widget ?
