The dashboard visualizes aggregated data from the underlying data source.
A dashboard item gets the data from the bound data source. The data is filtered with the data source filter and dashboard master filter. That data is raw dashboard item data or underlying data.
The dashboard aggregates raw data and produces the data to visualize - the displayed data.
Data Inspector enables you to view the raw and aggregated data. You can also use API methods to access them.
