I was casually sitting at my desk writing my first ever blog entry here when Tamás Földi walked past my desk. He asked me how much I know about Tableau and JavaScript, because he has a cool idea which he didn’t really manage to find the time to implement yet. He quickly briefed me into […]

One of the biggest myths of Tableau Javascript API is that you cannot use it inside Tableau Server. Some says that you need to embed your workbooks into external sites to leverage Javascript API. Well, don’t believe them since Tableau JS API works flawlessly in Tableau Server Vizportal with any workbook without any with some minor […]

Tableau’s Javascript API evolves fast. In just a few versions we have arrived from the basic embedding to an event based, fully asynchronous API. Maybe the last, missing piece was accessing the summary and underlying data (however most of us used the [crayon-58d5e8f52e804029427178-i/]  vizql controller to get the underlying data as featured in our excel […]

In this short tutorial I will go thru the basic steps of creating a project that uses Tableau JavaScript API. My intent is to show non-developers how the typical implementation workflow looks like.

No doubt that chess is one of my favourite game. It’s more than 15 centuries old but still fresh and enjoyable. Also no doubt that my favourite data visualization tool is Tableau so why not mix these two together? That’s the motivation of my new Tableau game, the Tableau Chess that is running entirely in a Tableau Public workbook […]

Regardless the sad facts I just can’t hate Business Objects. It belongs to my professional career: ugly but useful Web Intelligence reports, long running bursts for personalized mega excels – I still have nostalgic emotions. But what is bittersweet memory for me, is an everyday encounter for many of my customers. They still manage large SAP […]

TL;DR – Yes, this is an interactive Nokia like Snake game using Tableau Javascript API. You can play with the game at http://tfoldi.github.io/cljs-tableau-cnake/. I have to confess: I never used Tableau’s JavaScript (Embedding) API as of now. When we had to use it I always asked someone from my team to deal with that part […]

After my post yesterday on CORS vs Tableau vs WDC store on Gateway service Chris released his excellent article on unifying Tableau REST and JS APIs which reflected some of the stuff what I wrote. He is right in many things, but I would argue on the CORS easiness. In addition to my coding skills I […]
