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 (desktop application), for BI server (web application) are met. The web application supports visualizers if the BI server is installed in Windows 7 or later. Visualizer appearance may differ depending on the graphic libraries in use (DirectX 10 or OpenGL).

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.

Differences in Tree Map in Desktop, Web and Mobile Applications

In the web and the desktop applications the user can work with tree maps. In the mobile application based on Foresight Mobile Platform the user can only view tree maps. Depending on the application in use there are the following differences in tree map functionality:
