Back in 2018, Tableau released a much wanted feature to allow dataviz artists build dashboards with transparent backgrounds. The #datafam community quickly embraced this feature and started sharing some wicked vizzes. I’m not usually building fancy vizzes myself, but it did get me curious as well and led me to have my own creative artist moment:

Tableau’s out-of-the-box “Transparent Background” feature works nice and well when we are interacting with Tableau vizzes directly on Tableau Online GUI (or Server or Public), but some key questions I often hear are How to control transparency of visualizations when embedding in third-party apps…

If you have just invested in Tableau Embedded Analytics or joined Tableau’s OEM Program, here are some Community resources to get started.

My personal favourite is the Tableau Developer Program and, in particular, the Sprint Demo sessions. These are often run by Tableau’s own Developers and PMs who always provide a live demo with a sneak peak of what’s cooking first hand. Those sessions run every last Wednesday of the Month.

Here’s a list of some cool places to engage with the #datafam and #datadev communities 👪

Lately I’ve been noticing Auth0 IdP growing in popularity and an increasing number of Tableau customers have been adopting it. That’s no surprise to some of you, as Auth0 is one of the major challengers in the Gartner Magic Quadrant for Access Management (IDaaS - Identity as a Service).

Having said that, a barrier to adoption of Auth0 as an IdP for Tableau is their integration documentation is not very clear and that has discouraged some folks pursuing this integration. Additionally, as of this writing, some of the Auth0 docs refer to SHA-1 encryption, but Tableau Online now enforces SHA-256…

It’s quite frustrating when we are all set to embed your beautiful dashboard on our awesome web application and all we get is a nasty “414 Request-URI Too Long” error.

This is one of the cases where the error message tells us exactly what’s wrong, but it’s very difficult to figure out where the problem is and how to fix it. So this post is here to the rescue!


It happens when we want to apply filters before loading the viz, but we are passing way too many parameters and filters. When Tableau’s JS API is ready to send an…

This is an easy guide on how to install a self-signed certificate on Tableau Server that requires just 1 config file and 2 commands. It can also be applied to Windows machines (just make sure to add the OpenSSL directory to your PATH variable).

I will also show you how to install that certificate on a client computer (MacOS and Windows), to make it to trust the certificate while browsing Tableau’s GUI.

Self signed SSL certificates should only be used for testing or development purposes.

So, why bother? Well, there are a number good reasons why you might need to…

The process to configure Salesforce as Single Sign-on IdP for Tableau Online (or Tableau Server) can be super frustrating and difficult to debug.

In this short video, you’ll see a step-by-step and the main gotchas you might encounter when trying to integrate this method of Authentication to your Tableau Online and Salesforce Connected App.

You’ll also see in acton some of the tools I use to troubleshoot eventual SAML configuration errors. Namely these are:

The official Guide from Tableau on how…

This is perhaps my shortest and laziest post, but as they say, sharing is caring :)

I’ve recorded a couple videos explaining the process for embedding a simple Tableau view in Salesforce using VisualForce page component.

The first shows the process of creating a VF component and embedding Tableau into a Salesforce page:

And of course, this wouldn’t be complete if we had not shown how Tableau would look embedded in Salesforce Community Cloud, how to implement RLS (Row-Level Security) and how to leverage Salesforce Identity as the SAML IdP for Tableau Online or Tableau Server, to provide a SSO (Single Sign-on) experience:

Let me know what thoughts and what you’d like to see in a future post :)

As we continue to observe companies migrating their workloads to the cloud, fans of the traditional relational model, who also need a globally-distributed database, may find Google Cloud Spanner offers an irresistible combination of those things.

What was missing until now was the ability tap and explore this amazing database with the most awesome Visual Analytics Platform in the planet 😊.

Not familiar with Spanner? Here is a short overview from GCP Blog:

A couple years ago I created a Tableau Web Data Connector (WDC) for Swedish House prices. A number of my customers have been using it since then on a daily basis. It allows one to retrieve prices of properties sold anywhere in Sweden since several years back, as well as the houses currently for sale on the market.

One customer has used this data with Machine Learning to predict the prices these houses might end up selling for. Now they want to generalise their algorithm to provide a price estimate for a wider area, e.g. the postal code, rather that…

If you are reading this post, you are either on course to deploy an Internet of Things (IoT) Solution or you are among the thousands of business leaders that sees the potential that this technology is promising to deliver in the near future. Implementing the right IoT solution can bring tremendous value to your organization, but the key question is — where do you start?

Marius and I both work as Tableau Solutions Consultants, based in London, UK. We have been involved in a number of IoT projects to date. For instance, Marius has worked hand in hand with a…
