Cross filtering in Power BI is a feature that allows users to establish relationships between different data visualizations or components within a report. It enables interactive filtering, where selecting data in one visualization dynamically filters or influences the data displayed in other visualizations within the same report.
When cross filtering is implemented, selecting a specific data point in one visualization, such as clicking on a bar in a bar chart or selecting a category in a slicer, causes related visualizations to update accordingly. The connected visualizations are filtered to show data that corresponds to the selected data point or category. This interactive filtering provides a cohesive and synchronized view of data across multiple visualizations. By obtaining Power BI Course, you can advance your career in Power BI.

Cross filtering can be utilized in various ways to explore data and gain insights. For example, selecting a particular region in a map visualization can automatically update other visuals, such as a bar chart or a table, to display data specific to that region. This allows users to analyze data from different angles and drill down into specific subsets of information based on their selections.
Power BI supports both one-way and bidirectional cross filtering. One-way filtering means that selecting data in one visualization affects the filtering of other visuals, but not vice versa. In contrast, bidirectional filtering enables reciprocal filtering, where selections in either visualization impact the filtering of the other.
Overall, cross filtering in Power BI enhances data exploration and analysis by enabling dynamic and interactive connections between different visualizations, allowing users to uncover relationships, patterns, and insights within their data.
