It’s a common trope in the data analytics community to tsk tsk at any mention or appearance of the poor pie chart. There’s no other chart type that collects such derision and disdain. But why? Let’s tackle the pie chart and explain how it is...
In the final installment of this series on time-based comparisons, we are diving into comparing a single day’s performance against the historical performance for that particular weekday. To clarify the purpose of this post, suppose that the most recent day you have recorded is a Wednesday....
Tableau’s Device Designer helps you lay out dashboards to fit different screens, but designing for mobile is about more than screen size. Once you’ve sized and arranged everything, you aren’t done until you consider how mobile interactions differ from laptop or desktop computers. Let’s go through...
Quite frequently, students in training will ask “How do I make a gauge in Tableau?” While it's possible, it's not one of the default chart types in Tableau and can be somewhat time consuming. Instead, I recommend using bullet graphs, but why? What is it about...
Here’s a question that came out of a class from one of our other trainers: “Student wants a running sum to restart every time the value drops to zero.” How very interesting – a table calculation with a conditional scope. Let’s tackle this problem. Scope & Direction First, let’s...
One of my favorite announcements at TC16 was the new ability for Tableau to natively read shapefiles. Shapefile (.SHP) is a data type used for storing maps. This feature totally revolutionizes the things we can accomplish with our maps inside of Tableau. For more information on using shapefiles...
Ah, the month-on-month comparison. I’m not going to bore you with a sermon on the ins and outs of monthly comparisons, but I do want to explain what this particular variation accomplishes. In my previous post on comparing an incomplete week to the same days of...
The latest question from Tableau Training comes from Andy, who was in a DII: Intermediate course in Toronto, Ontario. “I need to match the colors on my charts to my company’s style guide. Is there a way specific colors can be chosen rather than the default...
For the past few months, I’ve been working with a client for whom tracking performance is a matter of life and death. Okay, maybe it’s not that dramatic … but they care a lot about player engagement and revenue streams for the video games they...
Time for another question from Tableau Training, this time a question asked by Daniel from a DII: Intermediate course in Kuala Lumpur, Malaysia: "I want to show my actual sales on a line graph, but I also want to combine that to show budgeted sales after...
In our final article in the Deep Dive on Dates, we’ll explore how to take a start date for different products and normalize it to a wee- by-week comparison from week one forward. This article was inspired by one of my Desktop I: Fundamentals students from...
For this article in our Deep Dive on Dates, we’re going to build a filter in the form of a calendar. Our user can select an entire month or a series of days to create a subset of data on the dashboard. Here’s a preview...
Above: The InterWorks Europe crew onstage. Thrilled does not cover it! With over 300 Tableau partners attending this year's EMEA Tableau Partner Summit, InterWorks were delighted to be awarded Services and Training Partner of the Year for the second year in a row. So, what does that...
Let’s continue our exploration of dates in our Deep Dive. In Part 6, we’re going to focus on how we can create rolling dates. A rolling date is taking a specific date, such as order date, and then adding a certain amount of days, months or...
Let’s continue on with our Deep Dive into Dates. This article, we’ll explore custom dates. The name admittedly is a bit of a misnomer and only really make sense if you understand date parts and date values. Make sure to catch up on this series...
We’re continuing our Deep Dive into Dates with an examination of the Exact Date value. Remember to catch up on the previous three articles where I introduced dates (discrete vs. continuous) and some key date functions. Let’s get started! Exactly What is Exact Date? In our first...
We’re continuing our Deep Dive into Dates with further exploration into date specific functions. In this article, we’ll cover DATEADD, DATEDIFF and DATETRUNC. My goal is not only to show you how to use them but to give you some real world examples of when they’d be...
In the first article on the Deep Dive on Dates, I introduced some of the basic concepts of dates. Specifically, we covered discrete vs. continuous dates, dart parts vs. date values and some basic date functions (DATEPART, YEAR, MONTH and DAY). In this article, we’ll...
Dates are one of the most confusing topics that come out of Tableau training. What is the difference between a continuous date and a discrete date? What is the difference between those and normal continuous and discrete fields? Why isn’t my date field showing up...
Here’s a question I got from a student named Summer in a DII: Intermediate course in Hong Kong: "I want to show all of the cities in the United Kingdom for a particular measure but only show city name labels for the top five." Awesome question! Let’s...
