Providing Data
This topic describes how to bind the Pie Map dashboard item to data using the Dashboard Designer.
The Dashboard Designer allows you to bind various dashboard items to data in a virtually uniform manner (see Bind Dashboard Items to Data for details). The only difference is in the data sections that these dashboard items have.
The image below shows a sample Pie Map dashboard item that is bound to data.
Note that the Pie Map provides two data item groups for data binding: DATA ITEMS and TOOLTIP DATA ITEMS. Tables below list the available data sections.

Pie Options
The Pie Map dashboard item allows you to take into account the weight of pies. In this case, the relative sizes of the pies depend on the corresponding summary values.
To enable this capability, use the Weighted Pies button in the Design ribbon tab.
Coloring
In Default color mode, the Pie Map dashboard item colors its segments in the following way:
If the Pie Map dashboard item contains arguments (the Arguments section), different argument values are colored by hue. If the Pie Map dashboard item contains only measures (the Values section), values corresponding to different measures are colored by hue.
The image below illustrates the Pie Map dashboard item whose argument values are painted in different colors. A special icon (
) on the data item shows that color variation is enabled.
Legends
The Pie Map provides two types of legends used to identify map objects - color and weighted legends.
