Tableau Software is an R&D heavy company, they’re just continuously throwing new features and releasing new versions. But what if some of our colleagues or clients are still not upgraded to the latest Tableau Desktop version? How can we share our superb new workbook? XML Hacking? Jeff’s converter tool? Forget all.

One thing that I realised in Austin: I’m not a Tableau Desktop guy. I’m struggling sometimes even with the easiest densification calcs and my dashboards generally suck. What can I do? Learn Desktop, deep dive and share my findings. Well, I did and the results are below. Going back to Austin. I spend two hours in […]

Two weeks ago I was lucky enough to visit some of my new and old customers in the sunny Bay Area. To make it more interesting I opted for a short presentation at Netflix to talk about Tableau Server Architecture, Abstract Query Caching and Fusion plus dashboard optimisation.

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-58d5e84e0f6e4751917680-i/]  vizql controller to get the underlying data as featured in our excel […]

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?

Last week I had the opportunity to show some of our solutions at ISATUG (International Server Administration Tableau User Group). One of my topics was graceful restart, because, yes, I still find it so useful that I want to share this goodie as much as I can. And to share something that actually works in practice […]

As of now there is no official support from Tableau Software to do black magic like this, but yes, you aren’t here for official supported stuff. You are here for actual solutions.
