Defines metaData attached to the Defines flag that determines if empty series are produced. Defines a Grafana time-series value data. "datapoints":[ [622,1450754160000], [365,1450754220000] ] This represents the MetaData Attached to a This structure is serialized and returned to Grafana via JSON. It needs to match QueryResultMeta in Grafana to avoid Grafana removing any MetaData Defines custom historian metadata. Represents a custom MetaData Record created by the openHistorian The Longitude of the original Signal The Latitude of the original Signal The name of the PMU Reads series of instances for the same time interval. Creates a new . Source series to scan. Time tolerance for data slices in Unix epoch milliseconds. Gets a flag that determines if data read has been completed. Gets time tolerance for data slices in Unix epoch milliseconds. Reads next time slice from the series set. Set to true to only publish last value per-series in time-slice for specified ; otherwise, false to publish all series values since last slice. Next time slice.
