Design ideas?

Question

Hello,
I am having a design issue.  I have an application that monitors 1-8 devices at a time and graphs the output from the device.  I created a user control that handles the connection, reading, and graphing for a device.  My issue is now how to design a interface to display the graphs.  I tried using just a single form that has 8 user controls but the issue is there is not enough space to display all in a decent size.  Also I think the user will want to move and rearrange the graphs.  Does anyone have a framework or suggestion based on their experience?
Thanks.
