Real time data in MATLAB

I have a piece of code that collects data from a hardware. I am trying to display the data real time. The hardware gives data every 1/512 sec. But plotting the data makes the system really slow. Is there a way to plot real time data using multithreading or multiprocessing, such that the data rate is not affected plot is remains real time.
