A smooth data line can be plotted...

Smoothed data example

The smoothed values can be calculated from...

  1. A moving average with a user entered 'window'. A 7 day window will give the average of all readings in a week, and 1 day will give the average of all data in a day.
  2. A digital filter with a user entered factor (0-1) that will give more or less smoothing. A 'Jump' value can also be entered - if the sensor value changes by more than this value the smooth values will be returned to the sensor value - essentially the jump in the values will not influence the smoothed values.

Use LoggerMenu/Calculated to set options.
