The visual of the matrix is comparable to that of a table. The data in a table is flat, which means that duplicate values are displayed and not aggregated. A matrix supports a stepped pattern, which makes it easier to show data meaningfully over multiple dimensions. The matrix gathers the data for you and allows you to drill down.
In Power BI Desktop reports, you may construct matrix visualizations and highlight components within the matrix with other visuals on the same report page. You can cross-highlight rows, columns, and even individual cells, for example. Individual cells, as well as multiple cell choices, can be copied and pasted into other programs.
You can create new calculations on existing tables using the modelling capability, and these columns can then be displayed in Power BI visualisations. This enables companies to create new measures and perform bespoke calculations for them.
