What you do with the data? store in a file also, or just plot into a moving
long bar-graph?
I imagine you are plotting vertical bars side by side, every reception, and
moving it to the left, is that it?
This can be done pretty easily in Visual Basic, even saving in a buffer,
storing in a file, comparing, taking average values, alarms, doing
statistics (max / min / standard deviation, etc).
