Overview

Serial differencing is a technique where values in a time series are subtracted from itself at different time lags or periods.

Examples:

Passing the options as a Hash

aggregation :thirtieth_difference do
  serial_diff buckets_path: 'the_sum'
end

Passing the options as a block

aggregation :thirtieth_difference do
  serial_diff do
    buckets_path 'the_sum'
    lag 30
  end
end
