Data Types

A dimension column accepts values of any type:

Type

Example

Description

string

Displays string values.

numeric

Displays numeric (integer or float) values.

date

Displays date-time values. For these values, you can change a group interval. Open the relevant data item's menu and use the Group Interval property in the Binding group.

boolean

Displays boolean values as true or false.

object

The dimension column can display images if it is bound to a data source containing images. You can choose whether the dimension column shows data as images or text (strings that encode images in the base64 format). To do this, open the relevant data item's menu and use the Display Mode property in the Options group.

In any case, the dashboard does not summarize the dimension values, but groups identical values.
