Bubble Tree

A bubble tree displays hierarchical data as a set of interrelated bubbles. Each hierarchical branch is represented with a bubble related with bubbles that are elements of the same hierarchical level. All elements of the same branch and the same hierarchical level form a circle, the center of which shows the parent element of the hierarchy. Each bubble's diameter is proportional to the 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 are met for the desktop application, and to BI server for the web application. The web application supports work with visualizers if BI server is installed on Windows 7 or later. The visualizer may look differently depending on the DirectX 11 or OpenGL 3.1 graphics libraries in use.

Operations with Bubble Tree

In the Selection group of tabs map elements of metrics dimension and the following bubble tree parameters:

Bubble fill color. Select the Color radio button on the dimension tab and select the element, which values will be used to determine bubble fill.
Bubble diameter. Select the Size checkbox on the dimension tab and select the element, which values will be used to determine bubble size.

The bubble tree will be rebuilt according to the specified parameters.

NOTE. The option is available if the element that determines bubble fill color is determined in the metrics dimension.

Use the Color tab on the side panel.

The setup is similar to setup of the Map data view fill.

NOTE. The option is available if the element that determines bubble size is determined in the metrics dimension.

Use the Size tab on the Format tab group of the side panel.

Use the Tooltips tab of the Format tab group on the side panel.

The setup is executed similarly to tooltip setup for a bubble chart.

To set up formatting for color or size legend, use the Color Legend or Size Legend tab of the Format tab group of the side panel.

To drill down data, click the child bubble, to drill up data, click the parent bubble. A tree map will be rebuilt according to hierarchy of observation objects dimension.

To exclude data, select the Exclude item in the context menu of child bubble or parent bubble.

To exclude all data, except for the selected bubble,s elect the Exclude the Rest item in the context menu of child bubble or parent bubble.

To set up bubble tree style, use the Bubble Tree ribbon tab.

The setup is executed similarly to setting up the Bubble Chart visualizer style.
