pressure history chart
« on: December 17, 2017, 11:14:08 AM »
I don't understand the history chart. There are 7 columns each 3 hours apart with the rightmost the last reading. When the next reading occurs all 7 columns change readings and they all seem to be random numbers. None of the readings seem to move to the left as I would expect.
