If you come from an Excel background, you’re probably familiar with the classic “Nested IF” statement. Nested IF statements are possible in Tableau, but they look a little different. Check out the video below to learn how to write these in Tableau (and some formatting tips for keeping them clean).
I recently received an email from a blog reader who was trying to solve a problem I’ve come across several times. He was representing populations on a map of the world in a chart that looked something like this.
I’ve known for several years that Google Sheets is the only data source which Tableau Public can automatically refresh for users. Until a few weeks ago, I had never tried to set up a living connection between Tableau Public and a routinely updated Google Sheet. It turns out that Tableau Public is good at holding up it’s end of the bargain, but keeping Google Sheets updated isn’t as simple.
I recently learned something crazy about Tableau. If you add a total to your worksheet and then try to filter another worksheet by selecting a total value, it doesn’t work! Maybe you’ve experienced this too and thought you were crazy. The unexpected solution to this problem is to add a separate total worksheet to a dashboard to use as a filter action. Tableau’s own documentation recommends this.
Does sorting in Tableau ever tick you off? Do your users have trouble finding the sort icon on the axis of a worksheet? Are your end users messing up your custom sorts and blaming it on you?
If you answered yes to any of the above questions, this week’s video is for you!
I recently saw some visuals built in a non-Tableau data visualization tool (not sure which one) that were utilizing emojis in dimension labels. I thought it was a fun way to mix up the standard labeling and text tables we usually see.
Tableau provides flexibility when working with dates, but sometimes getting it to do exactly what you want requires a custom touch.
If you’ve ever gotten stuck writing date calculations in Tableau, this webinar is for you!
One of the most popular blog posts on the OneNumber blog was Calculating Year to Date Versus Previous Year to Date in Tableau.
Tableau doesn’t have a great native feature for comparing year to date values to the same time period from the previous year, but it can be accomplished with a few calculations!
My Seattle Mariners fandom was cemented in the 1990s watching Ken Griffey Junior, Randy Johnson, Edgar Martinez, Joey Cora, Alex Rodriguex and others tear up the American League. Some of my fondest and earliest memories are attending games at the Kingdome with my dad.
Last week, I published a blog post about the power of compound interest and embedded related a Tableau Public dashboard (also below).
According to a number of questionable sources, Albert Einstein once said “Compound interest is the eighth wonder of the world. He who understands it, earns it. He who doesn’t, pays it.”
I’ve been working on a project with a client for several months where we are reporting against a sizable data source. Initially that data source took about 1-3 hours to extract locally which was okay. The faster the better, but I could live with it.
A few months ago, a blog reader, Om Parekh, reached out to me with a question. He was working on a project where he needed to compare each day to the same day the previous year. For instance, how did the third Wednesday in February, 2020 compare to the third Wednesday in February, 2019?
While working with personally identifiable information, you may need to suppress sensitive data. Let’s say that you are working with healthcare data and want to suppress patient names.
There’s an age old trick for Tableau Server published content I was recently reminded of and wanted to share. You can quickly and easily export a pdf, png or csv of a Tableau worksheet or dashboard by appending the file type at the end of a Tableau Server URL string. However, there are a few tricks to be aware of so let’s take a look.
I was recently working on a project that incorporated building management. One aspect of the management of the buildings was to ensure that regular inspections were done on each floor of each building weekly.
