How to take and display auto-updating screenshots in Tableau Public dashboards

Learn how you can take scheduled screenshots of online content and automatically display the latest image in your Tableau Public dashboard with PagePixels.

Introduction

PagePixels is a screenshot automation tool that you can use to automatically take screenshots and dynamically display the latest image in a website, app, or BI platform, including Tableau Public.

You can accomplish this by scheduling a screenshot in PagePixels and using an Embed URL in a Tableau Public Image object element.

A PagePixels' Embed URL is a single web address that always displays the most up-to-date image for a scheduled screenshot configuration.

PagePixels is free to start and this tutorial demonstrates how you can take daily screenshots of a random XKCD comic and display the image in your Tableau Public dashboard.

How to capture and embed auto-updating screenshots in Tableau Public

To take daily screenshots of a web page and display the latest image in a Tableau Public dashboard:

1

Create a screenshot

Log in to your PagePixels account, and click the "+Create Screenshot" button.

Save Screenshot

Click the green "Save Screenshot" button (top-right).

Click the clipboard icon to copy your configuration's Embed URL.
