pywr.recorders.AggregatedRecorder

class pywr.recorders.AggregatedRecorder(model, recorders, **kwargs)

This Recorder is used to aggregate across multiple other Recorder objects.

The class provides a method to produce a complex aggregated recorder by taking the results of other records. The .values() method first collects unaggregated values from the provided recorders. These are then aggregated on a per scenario basis and returned by this classes .values() method. This method allows AggregatedRecorder to be used as a recorder for in other AggregatedRecorder instances.

By default the same agg_func function is used for both steps, but an optional recorder_agg_func can undertake a different aggregation across scenarios. For example summing recorders per scenario, and then taking a mean of the sum totals.

Parameters

modelpywr.core.Model

recorders: iterable of `Recorder` objects.

The other Recorder instances to perform aggregation over.

agg_funcstr or callable, optional

Scenario aggregation function to use when aggregated_value is called (default=”mean”).

recorder_agg_funcstr or callable, optional

Recorder aggregation function to use when aggregated_value is called (default=`agg_func`).

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
