As Tableau Developers, we hate to see our work flattened and shoved into a PowerPoint file. We love to see our work displayed in it's fullest, greatest ways - full of filters, parameters and tooltips for our users to play around with. Occasionally, though, we have a few...
The Drawing Tool has been incorporated into CBI Studio by InterWorks. Explore CBI Studio to see what’s new. What’s not to love about dinosaurs? Their size, their teeth, their mystery – they still capture my imagination just as they did when I was six years old...
We all know that TC15 brings together quite the variety of people from around the country and even around the world. The question, however, is where exactly are all these people coming from? I managed to get my hands on some data surrounding this year's attendees...
If you're keeping tabs on the latest and greatest communication and collaboration tools, you've no doubt heard of Slack. It's everything IM should be and so much more. With near unlimited customization and integrations, Slack works fantastically in pretty much any environment for a wide variety of...
The 2015 Tableau Conference is just a few days away. While it isn't the first time the conference has been in the City of Sin, it will be the first conference for many of you and possibly your first trip to Vegas. During my years in...
Tableau purchased Power Tools in 2019. Contact Us for more information. This has been a strange year for me. After the success of Tableau Your Data!, Wiley was keen on a second edition. I thought writing an update to an existing book (the first one required a year)...
TC15 is rapidly approaching, and roughly 12,000 attendees are expected at the festivities. The vast majority of those attendees will be flying into Las Vegas, and there will be plenty that don’t travel very often. They may find themselves on the plane wondering what the proper etiquette is...
Here’s the next item on the Performance Checklist: "Avoid row-level calculations involving parameters." Let's first take a look at what row-level calculations are. Row-Level Calculations Row-level calculations, also known as record-level calculations, operate on every record in the underlying data. An example of a row-level calculation is an IF...
TC15 is coming. With around a week left until conference time, you’re probably thinking that you have plenty of time to get everything together. You’ve already packed everything (you’re THAT excited), the travel logistics have long since been figured out and you’ve successfully pawned off your...
While most of my friends would agree my athletic abilities leave something to be desired, this deficiency does nothing to disparage my passion for enjoying all kinds of sports (In case you were wondering how long we have to wait until the first Hoosier basketball game …)....
I joined InterWorks the same day as Ken McBride, and I wouldn’t have described either of us at that point as Tableau black belts — though we’d sure joined the right dojo! Before long, we were both traveling the world doing Tableau training and consulting,...
If you embed your Tableau analytics dashboards through either a straight embedded i-frame or with the JavaScript API, upgrading your Tableau Server to 9.1 will cause some unexpected grief. But it’s fixable. After upgrading Tableau Server to 9.1, I was getting this error: Refused to display 'https://path/to/my/tableau/dashboard?:embed=y&:showVizHome=n&:tabs=n&:to...
Tableau does a great job of connecting to a variety of databases, but it sometimes needs help on the database end to get the results we need to make hot visualizations. One such example showed itself when connecting to Google BigQuery. The issue? Count distincts. BigQuery doesn't handle count distincts like one...
I've had the pleasure of working with a large number of Tableau Server users and administrators, and by far the most common phrase I hear is "What the [expletive redacted] is up with permissions?!" Permissions in Tableau Server are very simple, given two conditions: Forget everything you...
Tableau Driver's Ed is a new blog series in which we explain InterWorks' unique take on Tableau Drive, a new methodology for enabling self-serve BI in the enterprise. For the full list of posts, check out the Tableau Driver's Ed channel. “The trouble with programmers is that you can...
Next up on the list of ways to make your dashboards be the best they can be, we take a closer look at blended calculations: "Limit blended calculations. They require sequentially querying multiple data sources and can be time-consuming. Where possible, create a view on the...
Let’s examine the following item on the checklist: "Use calculated fields carefully. Think about the data type as you code the calculation. Number and Boolean > date > string calculations when it comes to performance." This is another item that can quickly get you into performance trouble...
Quantified self visualizations predominantly focus on daytime activity, not sleep habits. Perhaps this is because it’s one of the most difficult things to accurately measure, or maybe it doesn’t seem like an interesting data set. But, anyone with a newborn in the house knows how...
Today we’re examining the following guideline: "Watch for useless clauses, e.g. ORDER BY. Tableau is going to re-sort the data once loaded anyway." Let’s get started! SQL Overview SQL, or Structured Query Language, is designed for managing data within a relational database. It is essentially composed of two parts: Data...
Currently, we’re going through the best ways to employ custom SQL and what to avoid. Here’s what we’ll cover today: "Avoid parameters in custom SQL in Tableau. Tableau wraps the custom SQL in a subquery that many databases don’t handle well. Consider building a view in the...
