Creating quadrant charts in Power BI just got a powerful upgrade. Thanks to the latest release, you can now shade each quadrant in a scatter plot with custom colors no custom visuals or third-party tools required. In this guide, we’ll walk you through how to set up a dynamic, fully native quadrant chart in Power BI that enhances visual storytelling and decision-making.

What Is a Quadrant Chart?
A quadrant chart is a type of scatter plot divided into four zones by vertical and horizontal lines. These zones help categorize data points based on two variables. A popular use case is to evaluate vendors or products, with quadrants labeled as Leaders, Challengers, Visionaries, and Niche Players similar to the Gartner Magic Quadrant.
Step-by-Step: Building a Quadrant Chart in Power BI
1. Start with a Scatter Plot
Plot your data using a standard scatter chart. For example:
- X-axis: Market Foresight
- Y-axis: Operational Excellence
Each data point could represent a vendor, product, or employee.
2. Add Reference Lines to Create Quadrants
Go to the Formatting pane > Reference Line:
- Add a X-axis constant line at value 5 (midpoint of your metric scale).
- Set the line width to 0 (to hide the line).
- Use the new Shaded Area option:
- For the first line, shade the area Before the line in gray.
- Add a second line at the same value and shade After the line in yellow.
Repeat the process for the Y-axis:
- Add a Y-axis constant line at 5.
- Use shading to complete the four colored quadrants:
- Use a color like blue to shade After the Y-axis line.
Combine colors wisely: Blue + Yellow = Green in the top-right quadrant.
3. Adjust Transparency and Style
To keep the focus on your data points:
- Increase shading transparency to around 75%.
- Format your markers:
- Set type to circle
- Adjust size and border to your preference.
4. Make the Quadrants Dynamic with Parameters
Power BI’s numeric range parameters let users interactively adjust the quadrant boundaries:
- Go to Modeling > New Parameter.
- Create Parameter X (1–10, default 5)
- Create Parameter Y (1–10, default 5)
- Add both slicers to the report page.
- Resize and style the slicers to blend in with your design.
- Link parameters to reference lines using the fx button in the reference line settings.
Now users can dynamically change quadrant cut-off points in real time.
5. Label Each Quadrant
Add meaningful labels to each quadrant:
- Use the reference line’s data label feature.
- Name your quadrants:
- Top-Right: Leaders
- Top-Left: Challengers
- Bottom-Left: Niche Players
- Bottom-Right: Visionaries
Use styling and spacing tricks (like invisible characters) to improve label positioning.
6. (Optional) Add Symmetry Shading
To add more depth:
- Add diagonal shading to emphasize dominance in one metric over another.
- Use subtle black-and-white gradients with high transparency for best results.
Note: Symmetry shading won’t adjust dynamically with your parameter sliders.
Why Use Colored Quadrant Charts in Power BI?
- Instant Clarity: Group and categorize data visually.
- Dynamic Filtering: Adjust categories based on real-time insights.
- Visual Impact: Highlight key insights through strategic use of color.
- 100% Native: No custom visuals or DAX hacks required.
Final Thoughts
This new quadrant chart technique using shaded reference lines is a game-changer for Power BI users. It’s visually powerful, easy to implement, and fully customizable—perfect for performance reviews, market analysis, or executive dashboards.
