Matrix with multiple starting rows that are not nested

Hi Katt1234 

Matrix visual behaves like a pivot table – each field you place in the Rows section adds a level of hierarchy. That’s why it nests fields when more than one is used.

However, if you're aiming for a flat, non-nested structure that shows multiple source columns alongside your measure (e.g., monthly average), one option is to switch to a tabular layout. You can do this by enabling “Show on rows” and disabling “Stepped layout” under the matrix visual formatting pane. Also, turn off subtotals if needed.

This way, your fields will appear in a single flat row and not as nested levels.
