This function adds periodic time series based on the long term scroller (see highlighted in red). This is a very handy functionality

This can be used to compare values of time series compared to what is “normal” on that date of different years.

Multiple different statistic types can be configured within this function, for each type a time series is added.

The statistics wil be calculated based on all values on the same day of the years, for all years included in the whole period of the long term scroller.

For this the long term scroller should be visible.

This is especially designed for time series with a daily time step.
