Customizing chart properties

After you create a chart, you can customize it by changing its properties.

You select the chart object in IBM® Cognos® Analytics - Reporting to view its properties. Some properties are dependent on the existence of other properties.

Note: Make sure your report is in Page design mode.

If you are familiar with using conditional variables, you can customize the chart to change its appearance or provide information in response to expressions or conditions.

As you edit the chart properties, Reporting provides you with a preview of your chart, using simulated data. This allows you to view your style changes without running the report. You can disable the chart preview in the options.

The following table shows some of the properties you can change in charts. These properties are available when you select the chart object unless specified otherwise in the Action to perform in the Properties pane column.
