Hi Gabe - It's a good idea to respond to your own post and then mark your answer as "correct". Tableau provides a way to "unmark your post as a question" but it has to be done within a very short time of posting.
Right now, your post shows up as an unanswered question.
PS Cool application of transparent elements!
Thanks Cathy, I thought I fixed that...but maybe I missed it.
I'll be sure to double check my ✓'s next time.
Thank you for quick tutorial
Is there a way, to push an image into the backgroung and build the dashboard over the image? Or graphs should be always in floating mode?
Thanks for sharing, Gabe!
Lots of folks happy with the launch of transparent backgrounds
OK, I completely give up.
I've used a 100% alpha PNG (transparent image) as an image object zone on the dashboard, and fixed the size of the dashboard (not something I like doing). I made the color of the dashboard "None". I also made the sheet color "None". Then I floated my worksheet on top (again, not something I like doing).
This had the desired effect - in both Desktop and Public versions 2018.3
But when I embed the viz onto my webpage, even though I made a div with the desired transparency rgba(0,0,0,0.75) the background of the viz object is forced white using the agent style sheet from the server.
Hi - This is great but we need the ability to adjust the opacity after the image is added to the dashboard please.
I know you can do this when adding the image at sheet level but I can't see the option to do it at dashboard level for a dashboard image
Also we need to be able to do the same with filters please. Looks a bit silly if I have all transparent graphs and then parameter drop downs with a background! Cheers

Hi all - has something happened to the transparent background feature in the latest update?
I built a dashboard using them which is no longer working correctly - the backgrounds are no longer transparent
Edit: Something went wrong with the bridge and I think this was related. Apparently a change was done on Tableau side and we had to restart the bridge!
You should be able to work around this by just including a floating layer (either a blank floating box that you add a color/opacity to, or use a saved png with the same intended styling color/opacity) and position it as a layer above the intended image using the layer orders panel in the Dashboard.
Is it possible to export the chart as transparent? Not just use them within dashboards?
Hi Pauline, Assuming you want something like a png export where the transparent alpha channel is maintained. Unfortunately, I don't think the image export feature is there yet where it can do it one step...
BUT, there is a workaround I've found, even before Tableau added the transparent background feature...
The ease of this depends on the complexity of the chart shapes, but if you export your view as an EMF (enhanced meta file), it can be opened in several programs where you're able to delete the background shapes.
Adobe Illustrator is probably the best program for it, but PowerPoint can also handle EMF's.
- Drag and drop the emf image into PowerPoint.
- Then right click on the image and say ungroup.. you'll get a warning, just go ahead and proceed.
- After it's ungrouped, you'll need to select the whole shape, and ungroup it again...possibly several more times to get all the various shapes separated out so you can easily select them.
- Once everything is ungrouped, start selecting the background shapes and delete them one by one until none are left... there's often a bunch of them, usually just white blocks.
- After that, select all the shapes, regroup, right click, and save as png...and no you have a Tableau chart with a transparent background that you can use in various publications or presentation needs.
Let me know if this works out for you
