  1. Click File > Open and find the report you just saved. Click OK.
  2. In the Palette, click and drag a File:/rd_chart.pngChart into the Report Footer band.
  3. Use the resizing handles to center and stretch the chart. You can also adjust the width of the band as shown in the following example: File:/rd_24.png
  4. Double-click the sample chart.
  5. The type of chart most appropriate for your report is a pie chart. In the top portion of the Edit Chart dialog box, select the pie chart icon. The pie chart properties that define its look and feel are listed in the left pane of the Edit Chart dialog box. Properties associated with the data in the chart are listed in the right pane.
