Categorical Filters (Text Filters)

Categorical Filters are based on text stored in columns in your database. Categorical Filters are sometimes referred to as Text Filters.

There are five types of Categorical Filter:

• Free Text

• Single Selection List

• Single Selection Drop Down

• Multiple Selection List

• Multiple Selection Drop Down

 

By default the filter will perform a partial match on all items starting with the entered text.

NOTE:  The default selection mode when the Text filter column has more than 30 values.

 

Single Selection lists allow all items to be displayed, or to apply a filter on a specific single selection.  The possible values are displayed alphabetically sorted under the filter title.

 

Single Selection drop lists filters show their status just below the filter title.

Click the down arrow to display all available choices for the filter.

You will see a set of radio buttons.  As you select a specified item, Panopticon Designer (Desktop) will update the associated visualizations to reflect your choices.

When the filter is applied the down arrow is updated to show the filter status, and the selected item is displayed.

 

Multiple selection lists, also display the list of possible values under the filter title.  In this case, one or many values can be filtered. Removing the check box selection from the “Select All” option, will remove all the selections from every item.

NOTE: The default selection mode when the Text filter column has 0 to 15 values.

 

Multiple selection drop down filters show their status just below the filter title. In the example to the right, we can see that there are three possible categories to choose from.

Click the down arrow to display all available choices for the filter. You will see a set of checkboxes. You can select or deselect any of the values available in the filter. Panopticon Designer (Desktop) will update the associated visualization to reflect your choices.

When the filter is applied the down arrow is updated to show the filter status, and the number of selected items are displayed.

NOTE:  The default selection mode when the Text filter column has 16 to 30 values.
