The Dashboard allows you to group dimension values and displays summaries for entire groups rather than individual values. You can arrange dimension values in different sized groups by specifying the appropriate group interval. For instance, date-time values can be grouped by year, month, quarter, etc.

This topic describes how the Dashboard groups data by default and lists the supported text and date-time group intervals. It also explains how to change the default group intervals.


Note that the Dashboard was not developed to visualize underlying, but already grouped/summarized data. You can obtain underlying data using the DashboardViewer or ASPxDashboard controls’ API. Refer to the following topics for more information:

Grouping String Values

When you add a string field to the dashboard item, the Dashboard combines identical field values into a single dimension value. You can also enable alphabetical grouping to combine field values by their first characters.

The following grouping intervals are supported for string values:

No Grouping

Each value is displayed “as is”.

The Dashboard groups unique underlying string values to a single dimension value by default. In this example, the Product field is added to the dashboard item.


If you add several fields, the Dashboard shows unique dimension value combinations. In this example, the Category and Product fields are added.



Values are grouped alphabetically (for instance, A, B, C, … Z). In this example, the Product field is added to the dashboard item.


Grouping Date-Time Values

Grouping allows you to combine underlying date-time values into years, quarters, months, etc. Note that the Dashboard uses the Gregorian calendar for grouping date-time values.

Date-time values are grouped by years by default. In this case, the Dashboard extracts a year from each date-time value and groups dates with the same year.


The image below shows how Dashboard groups date-time values by the same quarter in each year.


You can also add the same date-time field with different group intervals to display data hierarchically. For example, the image below shows how the Dashboard groups the Order Date field values when Year and Quarter group intervals are used.


Note that hierarchical data representation can be used with the Drill-Down feature.

The following group intervals are supported for date-time fields:


Examples in the table below are formatted using the default settings. See Formatting Data to learn how to customize format settings.

How to Change Group Settings

You can change group settings in the Dashboard Designer and in code.


Note that custom grouping is not supported in OLAP mode because data in a cube is already grouped and summarized.
