I am re-posting this because for some odd reason I posted first time in the wrong place, if this is wrong also I am not sure what I will do but here goes.

I agree that the problem should be split into small pieces and that verifying the serial side of things would be a good place to begin.

Can we see the instructions from the arduino that actually transmit the data, the fact you are using a micro controller gives you a certain degree of control over the serial protocol.

I assume the data is being transmitted in a loop, how fast is the controller repeating the transmission loop and at what baud rate.

If the transmission is too fast then it might not be possible to process the incoming and update a chart at the same time without buffer over run, which would be pointless anyway because you would be unable to read the chart as it updated at those speeds, this can be overcome by storing the data in memory and displaying it at a slower rate but this also has its limitations.
