Real-Time Signal Logging and Streaming by Using MATLAB

Signal visualization with and without real-time information

If you require the signal value and the time at which it reached that value, mark signals for logging with the Simulation Data Inspector or add a File Log to your model. See Real-Time Signal Logging and Streaming Basics.
