# Selector variables

If you drag a selector variable onto the dimension of a cube, the categories within that selector will be displayed. It is possible to edit the selector's categories displayed.

## Top N frequently occurring categories

This feature allows just the Top N categories to be returned on a dimension by dimension basis.

1. Open a **Cube** and drag the **Just-a-Cluster** variable onto the vertical dimension drop box
2. Right click on the same dimension and select **Edit Categories Displayed** option
3. Set the **Top N Categories** to **10** and click **OK**
4. Click the **Build** button
5. Right click on the People column and **Sort Descending**

The top 10 most populated categories are displayed and all other category counts are rolled into the Unclassified cell.

## Minimum category count

A further way to filter selector categories on a Cube dimension is to specify the **Minimum Count for Category** to only include categories from the variable that have at least the specified minimum number of records in the underlying selection.

1. Open a **Cube** and drag the **Postal District** variable onto the vertical dimension drop box
2. Right click to access the **Edit Categories Displayed** dialogue, and select **Minimum Count for Category**
3. Enter the required minimum category count - e.g. 1800 - and click **OK**
4. **Build** and **Sort Descending** to view the results
