By default, a bar chart displays rectangles without outlines, but you can change the bars to cones, tubes, or pyramids, or add a bar outline. To format a bar chart, navigate to the Series section of Format Chart. Use the settings to modify the bars, as shown in Figure 17‑5.

To add an outline to the bars or other risers, navigate to the Value (Y) Series section of Format Chart. In Series Outline, select a color.
