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.

Strictly Come Dancing Series 17; Report Version 2 is Here!

As I keep telling people and as I've said in previous blogs, I'm not a "Strictly" fan, I just happen to love the data and all the insights into it that Power BI can give you.

Understanding the “Analytics” Lines in Power BI

In our Power BI training courses, I show people how to add a Constant Line to a clustered column chart by using the Analytics section of the Visualizations pane.  I then explain that the other Analytical lines (Max, Min, Average etc) are “calculations across the totals”.  But what do I actually mean by this; what are these calculations?  I do feel that these Analytics Lines deserve a much better explanation so now is the time to turn the spotlight on… Read More
