Map<MetricEntity, List<MetricPlotPointEntity> > com.griddynamics.jagger.engine.e1.services.DefaultDataService.getMetricPlotData

(

Collection< MetricEntity >

metrics)

Return lists of points (values vs time) for selected metrics.

Parameters

metrics

- metric entities

Returns

map of <metic entity, list of points (value vs time)> for selected metric

Preferable way to get data. Data will be fetched from database in batch in single request =>
it is faster to get batch of metrics than fetch every metric in for loop
