PowerPoint Waterfall Chart "loses" chart characteristics


We have come across a very strange issue with Aspose Slides .NET. In the attached source code you’ll find an input.pptx that contains a waterfall chart - you can click the chart items, zoom in (it will stay sharp) etc. If we open the PPTX using aspose slides and immediately save it (without changing anything in the powerpoint!), the chart suddenly becomes an image, not sharp when being zoomed in etc. It loses its chart characteristics even though nothing has changed.

Any idea what’s going on there? :slight_smile:

Important: you’ll have to add the reference to Aspose.Slides.dll manually because I couldn’t keep the DLL in the upload because the file size would be too big then.

Kind Regards,
