Our tool currently only supports daily metrics, but the didDesigner is written in an extensible way such that other timeSeriesDataManagers can be created with hourly or yearly metrics with your own way of reading in KPIs and timestamps. Feel free to contribute with your own dataManagers, if you'd like.
