Fields

Field	Purpose
`SeriesRendered`	Number of series actually drawn after the `MaxSeries` cap
`PointsRendered`	Number of data points plotted after the per-series and total point caps
`LabelsRendered`	Number of data labels emitted before the `MaxLabels` budget stopped further output
`PathSegments`	Path segments emitted for series lines and markers
`Tagged`	`True` when the chart was emitted as tagged (accessible) content
`LabelsTruncated`	`True` when the label budget ran out and some labels were skipped

Usage notes

Pass a record variable to the THPDFPage.DrawChart overloads that take options; the library fills it during rendering
Check LabelsTruncated together with LabelsRendered to decide whether to raise THPDFChartRenderOptions.MaxLabels
Use Tagged to confirm that accessibility output was produced as intended for the document
