Change the Visual Style
After creating a visual on a dashboard, you can change its visual style. Based on the data source you are using, certain visual styles may not be available.
To change the visual style:
Select the visual in the dashboard or in the Visual Gallery.
In the Select Visual Type sidebar, select the visual style you want to use. Use the search bar at the top of the sidebar to quickly locate a style in the list. Type any letter in the search bar and sidebar is filtered to show only visual style names that include that letter.
