When would a tooltip be beneficial in a Power BI report?

A tooltip in a Power BI report serves to enhance the user's experience by providing additional context about a specific data point. When a user hovers over or clicks on a data visualization element, the tooltip can display supplementary information that is not immediately visible. This can include metrics, definitions, or insights that clarify what that data point represents or its significance in the larger context of the report.

Tooltips are particularly valuable because they help users better understand the data they are examining without overcrowding the visualizations with excessive information. This context can aid in interpreting trends, making comparisons, and deriving insights more effectively.

In contrast, hiding detailed data points directly or sorting data does not align with the function of tooltips, as these actions focus on data organization rather than contextualization. Additionally, creating a new table is a fundamental task associated with data modeling in Power BI, distinct from the interactive and contextual features provided by tooltips. Thus, the role of tooltips is specific to enhancing understanding through contextual information rather than altering the structure or organization of data.
