In Power BI, which visualization component can be used to convey important thresholds?

Using reference lines in Power BI is an effective way to convey important thresholds within a visualization. Reference lines allow users to set specific values that can be visually represented across a chart or graph. For instance, if you are displaying sales data, you could add a reference line to indicate a target sales goal. This provides a clear visual cue to users, enabling them to quickly gauge performance against that threshold.

Reference lines can be configured for various kinds of visualizations like line charts, bar charts, and others, allowing flexibility depending on the data being analyzed. They enhance visual interpretation by marking specific points of interest, which can lead to improved insights and decision-making.

In contrast, while data markers, data labels, and tooltips also add valuable information to visualizations, they do not fundamentally serve the purpose of explicitly indicating thresholds. Data markers highlight specific data points, data labels provide details about those points, and tooltips offer additional context on hover. However, none of these elements create a clear, persistent visual representation of threshold values like reference lines do.
