UPDATE: Below is a registration link for access to the Webinar. On 2 October I will be hosting a free webinar called “Introduction to DAX for Power BI”. I have trained literally thousands of people on the DAX language through my books, online training and live training. But everyone is […]
One common requirement I have come across a few times is to limit a Power BI visual to only show completed months and exclude the current active month. This is common if you load data on a daily basis, but some of your reporting is done on a monthly basis. […]
Level: Intermediate In my last article, I introduced the basics of the DAX FILTER() function. Hopefully that introductory explanation to FILTER() helped you get your head around what FILTER() is doing under the hood. With that knowledge in place, let me help you take your understanding to the next level. […]
Level: Intermediate FILTER() is one of the most important functions in the DAX language. It is quite a simple function and yet many people are scared off when they see it. In this article I will explain the basics of using the FILTER() function in DAX. Make sure you then […]
Today Microsoft announced that it is now supporting icon sets to be used for conditional formatting in Power BI. This feature has been available in Excel, like forever, and it great to see it available now in Power BI. Set Up Power BI Conditional Formatting Using Icons I have a […]
Level: Intermediate Pareto Analysis is a statistical technique that applies the Pareto Principle to data. This is more commonly known as the 80:20 Rule. The Pareto Principle is based on the presumption that a relatively small number of inputs (20%) have most impact on the results/output (80%). The 80:20 rule […]
I was doing some online shopping last week and saw a price slicer with a histogram to show the concentration of price points. I thought it was pretty cool, so decided to see if I could build this in Power BI. I came up with a solution that works, and […]
There was a new feature released in the June 2019 version of Power BI Desktop that I really like and I think warrants some explanation and review. The new feature allows you to pre-filter a slicer so that it only contains a subset of values that would otherwise appear in […]
I blogged about the various ways to use Measure tables and Measure Sub Folders in Power BI a few weeks back. I discussed why measure tables may be required, and also a few reasons why you may choose not to use a measure table. I also mentioned some alternatives to using […]
I often get asked about how to create measure tables during my Power BI course classes. This post will discuss the merits of measure tables versus storing your measures in the table where the data comes from. What is a Measure Table? A measure table is a dedicated table used […]
Way back in Oct-2016, Microsoft released a feature in Power BI Desktop that makes the process of creating groups much easier for the average user. I was reminded of this feature by an article by Reid Havens a couple of months ago. I blogged about various other ways of doing […]
Just a short post today to share with you a permanent fix to something that has been annoying me (maybe you too – but then again I am easily annoyed 🙂 ). Edit: read the comments below from Amir Netz from Microsoft where he explains why this change was made […]
I woke up Saturday morning to a lot of chatter and blog articles about an announcement that Microsoft made at SQL Bits. Microsoft is adding “Calculation Groups” to the DAX language. There are a number of blogs already that talk about the announcement, including Chris Webb and The Italians, but […]
I was answering a question for a student in one of my online training courses this week. The question was, “Do you know of a way in power query to efficiently extract YYYY-MM from a Date column?” This can be done ‘manually’ with multiple steps including: Extract the Year into […]
I was chatting to a few of my Power BI buddies during the week about when we thought the December 2018 update would be released. It seemed to me that under normal circumstances the new version is released on or about the first Monday (US time) on or after the […]
I had a question from one of my online Power BI Training students just this week who was struggling to import data from a large *.xlsb Excel file. I suggested she save the file as an XLSX file and try again – and that worked a treat. But the question […]
A few weeks ago I wrote an article introducing dataflows in Power BI and discussed why you should care about them. There are a few questions that have been spinning around in my head since then, significantly: What implication is there to the Power BI Golden Dataset as a result of […]
Microsoft recently released a new feature in Power BI called “Dataflows”. You may have seen it pop up in a recent release of Power BI Desktop under Home\Get Data\Power BI Dataflows (beta) as shown below. It is also visible when you log into PowerBI.com and go to an App Workspace […]
There is nothing worse than having a Power BI report that has 50% of the space taken up with slicers. When this happens, you only get half the page to visualise the actual data. But on the flip side, if you don’t have the slicers it can be harder for […]
Today Microsoft released the October 2018 update of Power BI Desktop. One of the fabulous new features that has been released is the ability to get a visual profile of your data in Power Query BEFORE you load the data. This new feature is typical of the type of development […]
