I have a prototype device that is feeding data into the serial port of my laptop. That is where the scope of my design ends, however I need to display the data recieved on a graph (x = time, y = hex value) to show I have suceeded. I have a program that will at least rip the data from the port and save it to file, but no display. Does anyone know of such a free program, or free to try that will allow me to do this rather than writing a Matlab or LabVIEW tool to display the data? I am looking at plotting 500K samples so a scolling window would be preffered.
