iVend POS - Data Shaping

This article describes how to perform various data shaping operations (such as grouping, sorting and filtering) in the Dashboard Designer. The article contains the following topics:
· Summarization
· Grouping
· Sorting
· Filtering
· Top N
· Formatting Data

Summarization

To obtain numeric values that should be displayed within a dashboard item, the Dashboard calculates a summary function against the specified measure.
By default, the Dashboard calculates Sum for numeric measures and Count for measures that contain another type of data.
You can change the summary function type for numeric measures. To do this in the Designer, invoke the data item menu and select the desired summary type. Less common summary types are organized in the More submenu.
Grouping
The Dashboard Designer allows you to group dimension values and display summaries for entire groups rather than individual values.
You can arrange dimension values in groups of different sizes by specifying the appropriate group interval. For instance, date-time values can be grouped by years, months, quarters, etc.
This topic lists the supported text and date-time group intervals and describes how to change the group interval. The following sections are available:
· Text Group Intervals - String values support the following grouping intervals:

Each value is displayed "as is".
