Displaying a chart without the table data
A report design that contains a lot of information in a series of tables with charts can often be more effective if it displays only the charts. To display only a chart, right-click anywhere in the table, and choose Hide Table. Choose Show All to re-display the table data. You can hide the table for report designs that contain regular charts and Flash charts.
