experimental.alignTime() function
experimental.alignTime() is subject to change at any time.
experimental.alignTime() shifts time values in input tables to all start at a common start time.
Function type signature
(<-tables: stream[B], ?alignTo: A) => stream[C] where B: Record, C: Record
For more information, see Function type signatures.
Parameters
alignTo
Time to align tables to. Default is 1970-01-01T00:00:00Z.
tables
Input data. Default is piped-forward data (<-).
Examples
Compare month-over-month values
- Window data by calendar month creating two separate tables (one for January and one for February).
- Align tables to
2021-01-01T00:00:00Z.
Each output table represents data from a calendar month. When visualized, data is still grouped by month, but timestamps are aligned to a common start time and values can be compared by time.
