How to plot data sent through serial port

[wenkeat]

actually if i'm not mistaken, what i need to do is make the graph update only after reading each complete value because it seems to be updating the graph at every byte of data received. how do i do this?

If you want to plot the data after obtaining all the 1024 bytes, you would need to plot the data outside the while loop. To do that you will have to tunnel the data through the loop, auto index the tunnel, and wire this indexed tunnel value to the waveform graph.

I hope this helps!
