Discover a New Feature in Microsoft Power BI: Matrix Visualizations
Posted August 30, 2017
Microsoft’s Power BI is a powerful tool that gives you multiple techniques for viewing and analyzing data. Data can be viewed using any of the various charts and graphs that come with the program, and even more visualizations are available for download from the Power BI community.
Microsoft has recently added the matrix visualization to help analyze parent-child relationships, such as those found within companies with departments or divisions.
This blog demonstrates how to use matrix visualizations to look at sales data from a standard ERP or CRM system Like Microsoft Dynamics 365.
Figure 1 shows “Product Sales by Region”, which has sales data for the United Kingdom and the United States. Use matrix visualization to drill down into each country by state, city, and zip code.
Figure 1 – Use matrix visualization to look at Product Sales by Region to see sales by country, state, and locale.
The column on the right shows the available visualizations, including “matrix”. The arrow on the left points to the actual matrix.
Also shown is a bar chart with the number of products ordered from each country and a map showing where the sales occurred along with a circle representing the relative size of the sales.
Figure 2 shows the setup information, such as Country, State, and Zip Code. Tax and Total were also selected for display. Fields can be added using drag and drop from the data.

Two buttons are available in the matrix: “Go to next level” and “Expand one level”, shown in Figure 3.

Select “Go to next level” to redraw the visual to show data based on States or Regions, as shown in Figure 4:

In Figure 5, we drill deeper, in this case showing City data for California:

Matrix visualization supports many levels of granularity, depending on how the matrix is configured.
Select the top left arrow to move back up a level or back to the top, as shown in Figure 6:

Expand the matrix with the “Expand one level” button to see summary data from the previous level. The example in Figure 7 shows the total for the United States along with the totals of each state below it:

Users can continue expanding levels up to the number of levels established in the matrix:

By right-clicking a visual, users can choose from options shown in Figure 9. For instance, users can include (show only) or exclude (remove) certain data from the view, useful to limit the report to only show data from sales in the United States:

Cross-highlighting allows users to discover trends. For example, by selecting California as the State, the map is redrawn to show exactly where the sales are occurring, as well as showing which products are responsible for these sales, as shown in Figure 10. This information can be used to develop strategies based on regions and product or to analyze the effectiveness of marketing strategies:

Users can easily customize the look of the matrix by adjusting features such as the matrix styles, colors, fonts, conditional formatting, and more.
