Hi there,
I am testing this with the latest stable version available (15.5.0).
I have a presentation with a slide that contains a chart. I have attached this presentation to this posting.
If I open this presentation via aspose and save the slide in a new presentation, I cannot access the data of the chart.
The following code resproduces the issue
var templatePath = Path.Combine(@"[YOUR_DOWNLOAD_FOLDER]", “AsposeRepro_CannotAccessChartDataAfterSave_Original.pptx”);
var pres = new Presentation(templatePath);
var slide = pres.Slides[0];
Presentation newPres = new Presentation();
newPres.Slides.AddClone(slide);
newPres.Save(Path.Combine(@"[YOUR_DOWNLOAD_FOLDER]", @“AsposeRepro_CannotAccessChartDataAfterSave.pptx”) , Aspose.Slides.Export.SaveFormat.Pptx);
Thank you for your help on this issue!
