This type of analysis provide simple statistics on the number of records falling in certain categories, including the number of rows, the number of null values, the number of distinct and unique values, the number of duplicates, or the number of blank fields. For more information about these indicators, see [Simple statistics](https://help.qlik.com/talend/en-US/studio-user-guide/8.0-R2024-04-and-earlier/simple-statistics).

It is also possible to add patterns to this type of analysis and have a single-bar result chart that shows the number of the rows that match "all" the patterns.
