The Statistical functions group defines dedicated graphing options shown in the combo box in the toolbar:

  • calendar aggregation (with associated time step).
  • relative aggregation (with associated time span).
  • duration exceedence (i.e. sorted descending).
  • duration non-exceedence (i.e. sorted ascending).
  • moving average (with associated time span).
  • central moving average (with associated time span).
    the (central) moving average function only works for true equidistant data (i.e. no daysOfMonths etc.)

    The difference between moving average and central moving average is that the central moving average uses values before and after the current value to calculate the average. Moving average only uses values in the past.
