Width Percent

Set the default column width for your timeline chart. This setting will be available If your selected Type is Column. 

The default setting is 100%, which means that the columns are as wide as permitted by the Max Unit Width of the X-Axis. Decreasing this value will result in thinner columns.

You can use Width Percent (Series X Configuration) to override the default Width Percent settings for a specific series, enabling you to find creative ways to visualize stacked columns, such as lipstick charts, box-and-whisker plots, and other combinations.
