Tree Map

A tree map allows hierarchical data to be displayed as a set of nested rectangles. Each hierarchical branch is represented with a rectangle that consists of smaller rectangles, which are subbranches. Area of each rectangle is proportional to value of the corresponding hierarchical element. Rectangle 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 Tree Map

In the Selection group of tabs on the side panel map elements of metrics dimension and the following tree map elements:

Rectangle fill color. Select the Color checkbox on the dimension tab and select the element, which values will be used to determine rectangle fill.
Rectangle size. Select the Size checkbox on the dimension tab and select the element, which values will be used to determine rectangle size.

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

NOTE. The option is available if the element that determines rectangle 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 rectangle 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 parent rectangle, to drill up data, click the child rectangle. The tree map will be rebuilt according to hierarchy of observation objects dimension.

To exclude data, select the Exclude item in the rectangle's context menu.

To exclude all data, except for the data of the selected rectangle, select the Exclude the Rest item in the rectangle's context menu.

To set up tree map style, use the Tree Map ribbon tab.

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