Removing charts in the Report Definition rule form
Save space in reports by removing redundant charts from report definitions. For example, you can remove a chart when you delete the data that the chart uses, or in a report that presents open cases, you can remove a chart when the cases are resolved.
In the navigation pane of Dev Studio, click Records, and then click .
In the list of report definitions, click the report definition that contains the chart that you want to remove.
Click the Chart tab, and then in the Chart editor section, click Remove Chart.
In the upper-right corner, click Save.
