	slide = presentation.slides[0]
	chart = slide.shapes.add_chart(charts.ChartType.CLUSTERED_COLUMN, 50, 50, 600, 400)

FAQ

Can I export a chart as a vector (SVG) instead of a raster image?

Yes. A chart is a shape, and its contents can be saved to SVG using the shape-to-SVG saving method.

How can I set the exact size of the exported chart in pixels?

Use the image-rendering overloads that let you specify size or scale—the library supports rendering objects with given dimensions/scale.

What should I do if fonts in labels and the legend look wrong after export?

Load the required fonts via FontsLoader so the chart rendering preserves metrics and text appearance.

Does export honor the PowerPoint theme, styles, and effects?

Yes. Aspose.Slides’ renderer follows the presentation’s formatting (themes, styles, fills, effects), so the chart’s appearance is preserved.

Where can I find available rendering/export capabilities beyond chart images?

See the export section of the API/documentation for output targets (PDF, SVG, XPS, HTML, etc.) and related rendering options.
