You can use default shapes provided by tableau as buttons to switch between dashboards but you cannot use custom images as action buttons in a dashboard. As if you add a image in dashboard tableau do not allow you to add actions on it and if you use image as a background in a worksheet and then add that worksheet in the dashboard then too you won't be able to access the whole image as button. Only the parts of the image where data is present will be involved in action event.
Hope it helps.
You are able to add an image to a dashboard and then create a url link on that image. So, if you know the url to the dashboard that you want to view you can inbed the url within the image and use that for navigation.
1.Is it possible to create a link directly on images to dashboard with in a workbook.We have tried using the sheets it works,But can we directly set the action on images for navigation?
2. Is it possible to make images transparent in tableau
1.You can place the images into the shapes folder then use them as shape in one navigation worksheet.Then create actions on them to get the appropriate dashboards.(in same workbook)
2.Tableau 8.1 supports transparent images but it is still beta.
We have tried the same it works.
Instead of importing the images in shapes can we directly set the action on image in dashboard?
. Only other option I see is using background images in a sheet.
No luck in finding a way to add action to a dashboard image.
