Standardmäßig wird beim Export des Diagramms in das SVG-Format das viewBox-Attribut nicht in seinem XML enthalten. Aspose.Cells für Python via .NET bietet jedoch die ImageOrPrintOptions.svg_fit_to_view_port-Eigenschaft, die beim Setzen auf true das Diagramm in SVG mit dem Attribut viewBox exportiert.
