Periodic aggregate
Periodic aggregates are similar to Rolling aggregates except that they downsample the data.
- If you have daily data and perform a Rolling aggregate using a window of one week with an average function, your chart will return a series with one point per day, with each point representing the previous week’s average.
- However, if you do a Periodic aggregate with a window of one week, your new series will have one point per week rather than one point per day.
