Real Time Plotting Tool ( Oscilloscope )

Hi,

I can't seem to get the SimPlot to actually plot something.
I tried loading both your arduino examples onto my Uno and neither of which display anything in SimPlot.
It would appears that it is opening the COM port but then after that there is not communication judging by the leds on my arduino board.
If I tried to connect to it via hyperterminal while SimPlot is connected then it tell me the port is in use basically. So I know if is connecting.
If I do connect to it in hyperterminal it sends out a whole bunch of data.
I'm hoping I'm not overlooking something simple here but there isn't all that many buttons to press.

Is the visual basic project available to the public?

Please see the screenshot below of the blank SimPlot.
