Vertical Color Strip:

• The vertical color strip serves as a visual indicator representing the related data tables within Spotfire.
• Enabling this feature allows users to keep track of the related data tables. When selected, a common-colored stripe appears on the title bars of visualizations that are based on related data tables.
• Additionally, filters in the Filters panel originating from these related data tables, which may interact with each other when manipulated, are also indicated with this color. For a reference, please refer the attached image.

To disable the vertical color stripe feature, follow these steps:

1) Open the desired Spotfire report.
2) Navigate to the "File" menu.
3) Select "Document Properties."
4) Check the box next to "Show a color stripe for related tables" to enable the feature.

Note: To remove the vertical color stripe from the DXP, simply uncheck the "Show a color stripe" option in the related tables section. This action will disable the feature and remove the vertical color stripe accordingly.
