The Pie Chart Diagram visualizes the value distribution for a certain Attribute on a Building Block Type. The Building Blocks are displayed as divided slices in a circle.

The arc length of each slice is proportional to the quantity of Building Blocks which share the same attribute value. Additionally, all Building Blocks can be filtered and colors can be user-defined.


Upon initial opening, a Pie Chart Diagram with a default configuration is presented. All further configuration is done interactively on the diagram. Use the tool area in the top left corner of the screen to configure your diagram step by step.

You can save the complete diagram configuration as public or private saved query. Whenever coming back to the diagram, the last configuration will be restored. The configuration is also stored in the browser URL.
