Publish to Web is not Secure - Today I want to issue a warning to anyone considering using Publish to Web to share corporate data internally within an organisation. Publish to Web is a standard feature on all Power BI accounts (free and Pro) – I first wrote about it two years ago here.  This is a great feature that is designed […] Read More
Text Filtering in Power BI - There are lots of different ways you can filter data in Power BI including: Slicers (with various configurations) Cross filtering from any visual object The filters pane on the right hand side of your report Custom visuals designed specifically for filtering Most of these standard filters require you to select on a specific value from […] Read More
Items NOT Selected in a Slicer? - I recently attended a school reunion (class of 1981 for what it’s worth – wow, I’m old!).  We all had a great time catching up, looking at old photos, taking new photos etc – how things have changed!  Anyways that got me thinking that it would be great to do something cool with Power BI […] Read More
New Power BI Reports from a Golden Dataset - This is an update to an article I first wrote on 18th April 2017.  At that time, connecting Power BI Desktop directly to the Power BI Service was just a preview feature. This feature is now generally available and hence it seems like a good time to update this post and talk about why you […] Read More
Changing Defaults in Power BI - Changing Defaults In March 2017, the Power BI team delivered a new feature that allowed you to change the colour defaults in a Power BI report using a custom colour theme.   I wrote a blog post over at PowerPivotPro.com at the time.   The drawback of this feature, as it was back in March, was that you needed to […] Read More
Conditional Formatting in Power BI - Level: Beginners I blogged on conditional formatting in Power BI Table visual here when it was released in the May 2016 Power BI Desktop update. At the time of first release, the conditional formatting was pretty basic with only 1 formatting option available. Over time, Microsoft has improved this feature, and now, it is available in both Table and […] Read More
Q&A in Power BI Desktop - Regular readers of my blog probably get sick of hearing me rave about the latest new thing in Power BI.  This month there is an absolute cracker – Q&A in Power BI Desktop.  In case you don’t know, Q&A is a natural language query tool that allows you to ask a question about your data […] Read More
Virtual Filters Using TREATAS - Level: Intermediate I have been aware of the TREATAS function for a very long time.  I have tried to understand how it works a few times but could never really work it out. I think part of the problem is the function name TREATAS is not very descriptive.  To contrast this point, the FILTER function […] Read More
Line Chart Conditional Formatting - I’m really pleased and excited to introduce you to Daniil Maslyuk (Twitter: @DMaslyuk).  I first met Daniil about a year ago (originally via email) as he was preparing to move to Australia.  Daniil made the plunge shortly there after and migrated to Australia (from Russia) – he now works as a Power BI consultant for Agile BI here in […] Read More
Killer Tips to Write Harder Measures - Level: Intermediate Background I was reading the questions at http://community.powerbi.com today and saw an interesting question.  In short the OP wanted to know if there was a way to identify (via a measure) if the row in a table had a colour =”Blue”, but also to check that there were no other rows with the […] Read More
DAX UNICHAR Function in Power BI - I first learnt about the new DAX UNICHAR function in Power BI by reading Chris Webb’s blog (which was also the inspiration for this article today).  One of the uses of the UNICHAR function is to be able to include non text characters inside visuals.  When you combine a logical set of these codes (icon sets) you […] Read More
Power BI Accounting Format of Dollars - Level: Beginners As I often say, sometimes it is the little things that can make a big different for some people – in this case Accountants.

New Functions – GENERATESERIES, SELECTEDVALUE - Level: Beginners/Intermediate In the August 2017 update of Power BI Desktop Microsoft released the new What If feature (first demonstrated at MDIS in July).  This new What If capability uses two new DAX functions to complete a task that you have always been able to do manually.  You still can of course still do it […] Read More
Happy Second Birthday Power BI - The 24th of July, 2017 is the second birthday for Power BI.  I thought I would take the occasion of its second birthday to reflect on all the great work that the crack Power BI team at Microsoft has done over the last year.   I think it would be a tough job working in […] Read More

My MDIS Data Analytics Challenge Entry - I was reading a blog by David Eldersveld last week where he was talking about his entry in the Microsoft Data Insights Summit Data Analytics Challenge.  I originally was too busy to enter however I was inspired by his article and thought I should prepare an entry albeit with only a few days to go.  […] Read More

Today Microsoft announced that it has listened to community feedback and has agreed to include this feature for all users again. […] Read More
Power BI Free is the Main Problem Here - I am an enthusiastic sponsor of Microsoft BI. I have been fortunate enough to build a new career off the back of the great products Microsoft has developed, specifically Power BI, Power Pivot and Power Query.  Having said that, I am definitely disappointed with the new licensing agreement changes have been released in the last […] Read More

I thought this would make a […] Read More
