How to Customize Sorting in Power BI Matrix Visuals: A Step-by-Step Guide
In data visualization, presenting information in a clear, logical order is as crucial as the data itself. Power BI, Microsoft’s interactive data visualization tool, offers a feature-rich platform for creating dynamic reports and analytics. Among its many visualization options, the matrix visual stands out for its ability to display data across two dimensions. However, default sorting options may not always align with your reporting needs. This article demonstrates how to customize sorting in Power BI matrix visuals by leveraging a sort order column, ensuring your data makes the impact it deserves.
Understanding Power BI's Matrix Visual
Before diving into the sorting mechanism, let's understand what a matrix visual is. A matrix visual in Power BI resembles a pivot table in Excel. It organizes data in a grid format, allowing users to analyze information across different dimensions and metrics. While Power BI automatically sorts data based on the values within each column or row, there are scenarios where a custom sort order becomes necessary to convey insights more effectively.
Why Customize Sorting?
Custom sorting in matrix visuals can drastically enhance the readability and effectiveness of your reports. Consider a sales report that categorizes products not by alphabetical order but by their contribution to the revenue, with high performers at the top. This custom sorting approach enables viewers to quickly identify key performers without scanning through the entire dataset.
Step 1: Creating a Custom Sort Order Column
The first step to customizing sorting in Power BI matrix visuals is to create a column in your dataset that represents the desired sort order. This could be a numeric column where each number corresponds to a position in the sort order.
For instance, if you're working with a dataset that lists product categories, you could add a column named 'SortOrder' that assigns a unique numeric value to each category based on your sorting preference.
Product Category | SortOrder
-----------------|----------
Electronics | 1
Apparel | 2
Home & Kitchen | 3
Toys | 4
Step 2: Configuring the Custom Sort Order in Power BI
After adding the sort order column to your dataset, the next step involves configuring Power BI to recognize this column as the basis for sorting your matrix visual.
- In Power BI Desktop, switch to the Model view.
- Locate your table in the Fields pane and click on the column that you want to sort (e.g., 'Product Category').
- In the Properties pane, find the Sort by Column option and select your new sort order column (e.g., 'SortOrder').
By linking your data column with the custom sort order column, Power BI now knows to arrange the matrix visual based on the values in the 'SortOrder' column.
Step 3: Applying the Custom Sorting to Your Matrix Visual
After configuring the sort order in the Model view, return to the Report view and add or select your matrix visual.
- Ensure your matrix visual uses the column you've applied the custom sort to (e.g., 'Product Category') as either a Row or Column label.
- The matrix visual automatically updates to reflect the custom sorting based on your 'SortOrder' column.

Conclusion
Custom sorting in Power BI matrix visuals is a powerful technique that enhances data readability and insight extraction, allowing users to present information in a meaningful order. By creating a custom sort order column and configuring Power BI to use this column for sorting, you can ensure your matrix visuals accurately reflect your analytical needs.
