The wellIdsJson on a ReportFigure is a JSON array of well IDs that determines which wells' data appears in the figure. For a time-series chart showing upgradient versus downgradient concentration trends, you would include only the wells relevant to that comparison. For a site-wide water-level map, you might include all wells at the site. Setting this list correctly prevents irrelevant wells from cluttering the chart and ensures the figure tells the story you intend. You select wells in Piper's figure editor, and their IDs are stored here.
