The visualizer is used to show hierarchical data as a bubble tree.
A bubble tree is a way to display hierarchical data as a set of interrelated bubbles. Each hierarchy branch is associated with a bubble that is related with the bubbles that are elements of the same level of hierarchy. All the elements of the same branch and the same hierarchical level form a circle, the center of which shows the parent element of the hierarchy. Diameter of each bubble is proportional to value of the corresponding hierarchical element. Bubble color also depends on value of the hierarchical element.
IMPORTANT. Before getting started with the visualizer make sure that system requirements to client computer (desktop application) and for BI server (web application) are met. The web application supports visualizers if the BI server is installed on Windows 7 or later. Visualizer appearance may differ depending on the graphic libraries in use (DirectX 10 or OpenGL).
A bubble tree enables the user to display two-value sets for hierarchical data:
The first value determines bubble color.
The second value determines bubble diameter.
Advantages of a bubble tree:
It enables the user to find interrelation between two factors in a hierarchical data structure.
It enables the user to visually show relations between hierarchical elements.
To insert the visualizer, select:
The Bubble Tree item in the drop-down menu of the Visualizers button on the Home ribbon tab.
The Bubble Tree button in the Visualizers group on the Insert ribbon tab.
The Bubble Tree item in the drop-down list of the New Block item in the dashboard's context menu.
Then select a data source for the bubble tree and set up dimensions.
Example of the Bubble Tree visualizer:
All operations with objects described in the Building Dashboard and Inserting and Setting Up Visualizers sections are available for the Bubble Tree visualizer.
