Bar
Horizontal comparisons, ranked values, and progress-style measures.
Line
Trend charts for time-series movement and multi-series comparisons.
Pie
Part-to-whole charts for a small number of segments.

OPF Catalog Notes
Aspose.Slides-supported chart types
The chart catalog publishes 26 records, one per Aspose.Slides ChartType that OPF supports, from https://github.com/OpenPresentation/opf spec/catalogs/chart-types. Other Aspose.Slides chart types (3D, cylinder/cone/pyramid, pie-of-pie, stock, surface, bubble, sunburst) are not yet OPF records.
Preset references
OPF snippets use chartPreset with the record id, letting the engine resolve the exact chart preset through catalogs.charts or the default pptx.gallery catalog.
Gallery metadata
Human guidance fields such as use_case, when_to_use, and when_to_avoid remain additive metadata; they do not replace or reshape OPF fields.
Export fidelity
Treemap, histogram, Pareto, box & whisker, waterfall, funnel, and map are Office chartex types; the current OPF PPTX exporter writes them as clustered column charts, and 100% stacked variants as stacked. Previews and exports for those types are approximations until the exporter emits native chartex.
