Changing the categorization of a column
In the Data panel and the Recommended visualizations window, the columns are by default organized into categories. The category of a column affects what happens when you drag the column and drop it on a column selector or drop target in a visualization. It also affects which kinds of visualizations are advised in Recommended visualizations. If the suggested category for a column is not your preferred category, you can change the categorization.
The different categories are Numbers, Currency, Time, Location, Categories, Identifiers, Text, Images, and Binary. Which categories are available depends on the data type of the column. For example, if the values in a column are integers like 4633, 4637, and 4638, the suggested category might be Numbers. This means that you can calculate sums or averages, or use other aggregation methods. However, these numbers could just as well represent, for example, employee numbers or purchase order numbers, and any aggregations would not be relevant. In these cases, the column values should be handled as Identifiers or as Categories instead.
Data panel, or the
Recommended visualizations window, right-click on the column whose categorization you want to change.
In the Data panel you can also open the expanded data panel and change the categorization for a certain column in the Categorize column as section of the column view.
- In the opened menu, select Change categorization.
In the list of categories, select the preferred category.
Only relevant categories can be selected. If a desired category is unavailable you may need to change the data type of the column first.
