A Datablock is the primary information holder, visualizing at least one metric from a data integration. To display your data the way you like, you will need to choose a data source, a metric and a date range (time interval). You can also go deeper and set granularity, aggregation, scale, format, etc.
Each datablock has a main interval (the primary date range for data visualization) and the option to add additional intervals (except ‘Main’ and ‘Interval’ datablocks). Additional intervals give you the ability to switch the date range for the selected metric to drill down your KPIs.
