Description: The panel legend in data visualization tools refers to the visual narrative that accompanies the data presented in a dashboard panel. This concept is fundamental for the effective interpretation of information, as it allows users to quickly understand the context and relevance of the visualized data. A panel can include graphs, tables, and other visual elements that represent metrics and statistics from various data sources. The legend provides descriptions, units of measurement, and other annotations that help users correctly interpret the information. For example, in a line graph showing server performance, the legend may indicate which line represents CPU usage and which represents memory usage, thus facilitating the comparison between different metrics. This clarity is essential in environments where decisions must be made quickly based on real-time data. In summary, the panel legend not only enriches data visualization but also enhances decision-making by providing a clear framework for interpreting the presented information.
