For each series in the source dataset:
- create a new series containing the same x-values, except for those in the range x0 to x0+skip which are left out (so that is the meaning of the 'skip' argument);
- for each x-value in the new series, calculate the average of the y-values from the original series in the range x to x-period (so that is the meaning of the 'period' argument).
