A report page tooltip shows a small report when a reader hovers over a visual. It can include a card, a trend or a table, and it receives the hovered data point's filter context. A regional sales bar can therefore show regional orders without adding another permanent chart to the overview.
Create a separate tooltip page, turn on Allow use as tooltip, then assign it in the source visual's tooltip settings. The page's content still needs measures that respond to filters. A measure that removes the region filter would show the same company total on every bar. Keep the tooltip short and readable; the reader can't treat it as a full page with scrolling. Verify both the assignment and what the measures mean under the hovered context.
