Aquiring graph data from realtime simulation

To run simulation from matlam I use sim function, which gets data from the model always after simulation is stopped. But what is the way of getting data in realtime simulation? In other words I have simulation with inf stoptime and want to plot graph in matlab, but not in simulink scope. Is there any way of doint this?
