Power BI Gantt Visual (Preview): First Look and Workarounds
I left project controls a few months ago, just in time for Microsoft to release a native Gantt visual for Power BI. Did that stop me from testing it the moment it landed? Of course not. Leaving project controls analytics doesn’t mean I’ve stopped being curious about the tools we use! So I built a…

Who Is in the Loop? Semantic Models, Meaning and People
FabCon Europe in Barcelona gave me plenty to think about, particularly as someone who has spent much of my career working with data and Power BI and is still relatively new to the wider Fabric ecosystem. One session that stayed with me was “Best Practices for Semantic Models in Fabric Data Agent”. I have spent…

Alt Text for Grouped Visuals in Power BI: What I Learnt from a Pull Request
It all started with a pull request for PBIR A11y CLI. PBIR A11y CLI is the command-line version of my PBIX A11y accessibility checker. John Kerski submitted a batch of improvements, including tests for the alt text check. One of his tests showed something odd: a group containing several elements, each with its own alt…

Building an APCA Contrast Checker in Power BI: A Perceptual Approach to Accessible Colour
After publishing my WCAG Colour Contrast Ratio Checker in Power BI, there was still one thing sitting at the back of my mind: APCA. I first came across it back in 2024, when I properly threw myself into colour accessibility. I even mentioned it in my session “Implementing Alternative Accessible Colours in Power BI Reports”…

How Accessibility Makes Power BI Usable When Everything Else Gets in the Way
Most conversations about accessibility begin with disability. That is understandable. Accessibility standards such as the Web Content Accessibility Guidelines (WCAG) were developed to remove barriers for people with disabilities, and that remains their primary purpose. However, accessibility is not only relevant when someone has a permanent disability. The way we consume information changes constantly depending…

Outlier Detection Done Right: Five Statistical Tests and DAX UDFs
This article started somewhere I wasn’t expecting. And yes… it’s a long one! But bear with me, it’s worth the journey. I started with a simple question about a few unusual spikes in some data, and somehow ended up building five reusable statistical UDFs for Power BI. So how did it start? Not long ago,…

Before AI Builds Your Power BI Report, Tell It This
AI is rapidly changing the way we build Power BI reports. What began with asking ChatGPT or Copilot to write a DAX measure or explain an error has evolved into something far more powerful. Today, AI can suggest report layouts, recommend visuals, generate measures, and even build an entire dashboard from a simple prompt. With…

Small Buttons, Big Problem: Fixing Target Size in Power BI Reports
One of the latest accessibility checks I’ve added to PBIX A11y looks at something many Power BI developers rarely think about: the size of interactive elements. Things like buttons, slicers, navigation items and clickable icons. At first glance, this might seem like a small detail. But when you stop and think about how people actually…

What I Learnt About Protecting User Data While Building PBIX A11y With Vibe Coding
When I began building PBIX A11y, I expected the difficult part to be the accessibility logic. It turned out the real challenge was something far less glamorous. I was using vibe coding, and Lovable was generating the application for me based on natural language instructions. This meant I could move quickly, but it also meant…

The Missing Rule for Power BI Layouts
Since I posted my article about minimum font sizes for different Power BI canvas sizes, I have been thinking about all the other UI elements on the screen. Surely they would behave similarly to font sizes? If font sizes need to scale proportionally to the canvas size to preserve readability and accessibility… then spacing, padding,…
