General support for data aggregation #59
Description
When components fetch data from a large timeframe it's possible that much data is loaded that is to fine. That couses long load times. On the other hand a preconfigured aggregation of data is not allways sutiable.
If data with date / time information is detected a option should apear at the component, that allows a aggregation. The user should be able to select:
- startpoint and endpoint (like in the General support for timeframes)
- intervall of aggregation (month, week, day, hour, minute)
- intervall should have a default value according to the defaults in SmartDatalyser/aggregation/intervallMedians
Aggregation should be done serverside, useing the existing SmartDatalyser functions.
Also general filters should be supported with this (see General support for data filter Ticket)
This functionality should be off by default (old behavior) but activateable.
