What is the function of a "Reference Line" in Oracle Analytics?

A reference line in Oracle Analytics serves as a visual aid that represents constant values for data comparison within visualizations. This tool is critical for enhancing the interpretability of data displayed in graphs and charts. When a reference line is applied, it allows users to easily discern how specific data points relate to a predetermined value, such as averages, goals, or thresholds. This comparison can highlight trends, identify outliers, or establish the context necessary for making informed decisions based on the data presented.

For example, in a sales performance graph, a reference line might represent the sales target, enabling users to quickly evaluate whether sales figures are above or below expectations. By establishing this clear point of reference, users can enhance their analytical insights and make more effective decisions based on the contextual relationship of their data to the reference line.
