Setting Up the Bubble Chart Visualizer

A bubble chart is a scatter chart, in which data points are replaced with bubbles. Bubble size is an additional data dimension.

IMPORTANT. Before getting started with the visualizer make sure that system requirements to client computer for the desktop application and to BI server for the web application. 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 11 or OpenGL 3.1).

Category axes and value axes match in a bubble chart. Horizontal and vertical axes are value axes.

In addition, in Foresight Analytics Platform, a bubble chart contains an animated timeline, which displays the frequency of values.
