#### Formatting the gridlines

The gridlines of a chart can be customized (pie, indicator, heat map and org charts do not have gridlines). To do this:

1. Right-click any chart element and select the desired entry from the Format Gridlines submenu to bring up the corresponding Format Gridline dialog.
2. Specify the line color, style, transparency, and thickness of the gridline.
3. When done, click OK to accept the settings and close the dialog.
