I know that I am able to change the color of the background of a dashboard. I would like to have a gradient of the color in it (like attached). Do you guys know maybe how to do it or if it is possible?
Gradient fills like this aren't natively available in Tableau. Instead you could create the gradient background as a PowerPoint slide, save that as an image (jpeg or png), then use that image in an image container on your Tableau dashboard.
