Adding an Image Button to Preview Viz on Phone

Currently phone is the de facto platform for viewing vizzes, especially for those public vizzes. Not surprising. However, it's not so easy to view vizzes on phone at all. Here is a little effort to make it a bit easier to view any viz on phone. This enables the greater distribution and dissemination of vizzes, and also makes it easier to check dynamic data on the go.

The solution is adding an image button at the top-left corner of your viz. With a single touch on the button, user will be able to preview the entirety of the target viz.

Try the image button in this viz on your phone: https://goo.gl/yqYDBv or click the image below to access the viz.

So, how to create this image button?

1.Publish your initial viz (without image button) to the Tableau Public server first and get the URL of the viz, such as the one below (ignore the string starting with ? and after.)
https://public.tableau.com/views/MexicoIntentionalHomicideRate2010-2017/MexicosIntentionalHomicideRate2010-2017

2.Create the image URL by attaching the following string to the above URL.
.png?:showVizHome=no

The resulting image URL will be 
https://public.tableau.com/views/MexicoIntentionalHomicideRate2010-2017/MexicosIntentionalHomicideRate2010-2017.png?:showVizHome=no

Give it a test before you go further.

3.Create an image object in dashboard with this image:

Note that the white area is transparent. Make the image object floating. Place it at the top-left corner of the target viz.

4.Fill the URL of the image object with the image link in Step 2.

That's it. Publish the viz again. And test the button.

On enterprise Tableau server or Tableau online, just add .png to the URL of your target viz. This will make the preview of any viz on phone a bit easier.
