What is the primary function of Reference lines in Power BI visualizations?

• A. To indicate potential outliers in the dataset
• B. To replace the axes labels in a chart or graph with custom lines
• C. To highlight specific data points or values
• D. To create subtotals and aggregate values in tables

Answer: (C)

Reference lines in Power BI visualizations serve the purpose of highlighting specific data points or values on a chart. By adding these lines, users can provide context or benchmarks against which the data can be compared. For example, a reference line can represent a target value, an average, or a threshold. This allows viewers to easily determine how actual values measure up against these highlighted benchmarks. In visual storytelling, this can be particularly useful as it enhances the interpretability of the data, guiding users’ attention to significant areas of interest or trends within the dataset. It supports informed decision-making by visually indicating critical thresholds or trends that are relevant to the analysis at hand.
