Description copied from interface: GraphModel

Retrieves graph data (GraphData) for the specified zoomLevel and {cod@ neededInterval}.

The model MAY choose return more data than needed, covering a larger interval than requested.
However, the result MUST at least cover neededInterval!
If the model delegates to multiple sub-models for different graphs, its aggregated GraphData object should use the intersection of the sub-model's GraphData.getInterval() as its own GraphData.getInterval().

Parameters:

zoomLevel - the requested zoom level

zoneId - the zoneId to apply when partitioning over time

neededIntervalX - the time interval requested by the client

displayedInterval - the time interval displayed by the client

Returns:

graph data
