Data Table Filters within Charts in Power BI

To show underlying data for a chart visualization in Power BI, follow these steps:

1. Select the chart visual that you want to view the underlying data for.
2. Click on the "ellipses" (...) at the top right corner of the visual to open the dropdown menu.
3. From the dropdown menu, select "Show as a table" option.
4. Power BI will then display a table with the underlying data for the chart visual. You can scroll through the table to view all the data.
5. If you want to export the underlying data to a CSV or Excel file, click on the "Export data" button at the top right corner of the table.

If  you need to show background data related to some point at the chart, use "Show data point as a table" from chart figure context menu.

The underlying data depends on selected Legend data field columns and source data table cannot be created by selecting several records from a chart.
