Adding a packed bubble visualization

A packed bubble visualization is similar to a bubble chart in which the bubbles are tightly packed rather than spread over a grid. You can use a packed bubble visualization to display a large amount of data in a small space.

Before you begin

Your administrator must make the visualizations available in the Visualization Gallery.

If you use Microsoft Internet Explorer to view visualizations, you must have Microsoft Silverlight 5 installed on your computer. Firefox or iPad users do not need Silverlight.

About this task

You add data to a visualization by inserting data items in drop zones.

When you add a visualization to an IBM® Cognos® Active Report, you can choose to render visualizations on the IBM Cognos server or on the client. When you choose to render visualizations on the client, additional drop zones appear for extra categories or values when all the required drop zones contain data items. You can use extra categories and extra values to filter data or set variables. Extra items are not visible in the visualization.

When you work with dimensional data sources, if the visualization does not contain a measure against which to plot data, you must provide one. For example, if you add a single member to the values drop zone, such as '2012', the default measure drop zone appears in which you must insert a measure.

Attention: The supported properties for a visualization are determined by the visualization definition.

Procedure

From the Toolbox tab , drag a Visualization icon to the work area.
From the Visualization Gallery, select the Packed Bubble icon and click OK.
From the Source tab , drag items to the appropriate location in the data container:
1. Drag a measure or a single value to the data container, under Values.
2. Under Categories, drag an item to plot as the bubbles.
3. Under Series, drag an item to apply as a category. Each item in the category gets a different color from the color palette.
