The caption on a ReportFigure appears directly below the chart in the rendered PDF. Use it to explain what the figure shows, what data period it covers, and any important caveats — for example, "Time-series plot showing benzene concentrations at downgradient wells from Q1 2022 through Q4 2024. Dashed line indicates the applicable MCL of 5 micrograms per liter. Non-detect results plotted at one-half the reporting limit." A well-written caption makes the figure self-explanatory without requiring the reader to cross-reference the section text.
