What changed

All updates
Feature updateHierarchy axes auto-expand and work with field parametersBar, column and line charts now support auto-expand on the hierarchy axis when it carries more than one column, matching the slicer and matrix behaviour, and the hierarchy axis now works with field parameters, both generally available from the October 2026 update. One parameter slicer can swap the fields a chart's axis and a matrix's hierarchy use at the same time.Feature updatePersonal bookmarks keep table and matrix column widthsPersonal bookmarks in Power BI now preserve the column widths you set on tables and matrices, including reordered and resized columns, so applying a bookmark returns the exact layout you saved instead of making you resize columns again.
