Somewhere around the end of July I was invited to show some magic from our consultancy portfolio in the Server Admin User Group’s virtual meetup. I choose (no, actually Mark choose) two topics: the first was automated query banding (practically server side search and replace to programmatically fill initial sqls for workbooks and data sources) while […]

SAP ERP systems are probably the best when it comes to robustness, flexibility and extensibility. However, two major issues almost always come up with SAP customers: the lack of operational analytics and the user interface which is… well… not the pinnacle of UI design. SAP constantly promises that they will replace the UI with something […]

It started with one of my colleague who managed a Tableau case from our end. His client was constantly dissatisfied: her workbooks were significantly faster with embedded data sources compared to published ones. Even if we told her that this is normal, this is the way how life works, so better accept it and let […]

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 […]

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. Tableau Desktop can do […]

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. I was super jetlagged but still I […]

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-59ed039c81e26778291815-i/]  vizql controller to get the underlying data as featured in our excel […]
