As most readers of my website would surely know, Microsoft Excel has had a dual axis line chart as a standard charting visual for many many (many) years. A dual axis line chart is needed when you have 2 sets of data to display with significantly different scales like the […]
Back in 2018 I wrote an article showing how to extract data from websites using Power Query in Excel. For simple websites this process is very straightforward.

Edit: 27th Nov 2019. Note applications for this job are now closed. Meet Jason, my full time trainer. It is 5.5 years since I left my 25 year corporate role at Coca-Cola and started my own business training and supporting the Microsoft self-service BI tools (Power BI, Power Query and […]
Last week in Orlando Florida, Microsoft held its annual Ignite conference. I have never been to Ignite but it is on my list of things to do in the future. There are always lots of announcements at this conference but there was one announcement that I haven’t seen much publicity […]
I stumbled across an interesting problem recently when helping someone on a forum. Here is the scenario. Assume there is a help desk that is logging tickets into a system. Each ticket is assigned to single staff member who is responsible to action that ticket. The requirement is that when […]

Its purpose is to act as a table filter parameter inside CALCULATE() as shown in the following example. Total Sales All Products REMOVEFILTERS() = CALCULATE([Total […]
I was delivering Power BI training in Melbourne last week and one of my students asked if it was possible to show on a report if any filters have been applied. It is a very good question because it is not always immediately obvious if filters have been applied or […]
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 […]
