the graphing refresh rate should be able to be controlled by the user and not auto ranged ( default of 16s)because if you are looking for intermittent lows or highs you need to have two people looking at the scanner to hopefully catch it, or at least change the auto ranging to a higher value (if possible) or allow it to be slowed down during play back after recording.

 thank you very much for the response!! looking forward to that update
