Power BI Conditional Formatting

I thought this would be an easy blog. Not much to say about using Power BI's Conditional Formatting. All it does is make visuals look more appealing by using pretty colours based on the data's values. How wrong I was! In fact there's so much to say that I've had to resort to a mini contents page using outline numbering and links to the relevant paragraphs. In fact, just like the old days of writing user manuals! So here goes… Read More

How did I do this? Firstly, my… Read More

The Key Influencers Visual Versus Strictly Come Dancing

The Key Influencers visual, introduced in February 2019, is Microsoft's first visual that uses "Machine Learning" to identify factors that influence the outcome of a particular metric. "Wow", I thought! The idea of leaving Power BI to do all the hard work in analysing my data seemed too irresistible to ignore, so I gave way to temptation and decided to give it a go. On the one hand, it's a very simple visual to construct (it only has 3 buckets;… Read More

Find a Value in the Previous Row

Recently I was asked by one of our clients to solve this question; how could they calculate the number of days between customers' transactions? Clearly, in order to do this calculation, you would need to find the transaction date that was previous to the transaction date sitting in the current row. You could then subtract the earlier date from the later date and return the days between them. It occurred to me, that such a calculation could have a more… Read More

Four DAX Functions You Can’t Live Without

Data Analysis Expressions, known as DAX, is the Function language that is used to solve data analysis problems in Power BI. DAX is used in the much the same way that you use Formulas to solve analysis problems in Excel. These expressions, when used in Measures, analyse our data by applying or removing specific filters from the data, filters that would be difficult to accomplish with the normal filtering tools in Power BI such as Slicers and Visual Level Filters.… Read More
