Documents display data values returned from data sources in data objects. Web Analysis documents can have multiple data objects, and each data object can have a different display type:
Spreadsheet
Chart
Pinboard
SQL spreadsheet
Freeform grid
Each display type has numerous prerequisites. Because SQL spreadsheets and freeform grids can be created only in Web Analysis Studio, you cannot change them.
Pinboards require traffic lighting definitions, so you can change spreadsheets or charts to pinboards, only if the pinboard definition is defined.
