I have a question.

But it not work - here is my code:

( i load a template file with an PIE Chart and i will change the type to a RADAR )

<br /> <br /> Presentation thePresentation = new Aspose.Slides.Presentation("pieTemplate.pptx"); <br /> <br /> foreach (IShape theShapes in thePresentation.Slides[0].Shapes) <br /> { <br /> if (theShapes is IChart) <br /> { <br /> IChart theChart = (IChart)theShapes; <br /> <br /> <br /> theChart.Type = ChartType.Radar; // this not work for me <br /> } <br /> } <br /> <br /> thePresentation.Save("export.pptx", Aspose.Slides.Export.SaveFormat.Pptx); <br /> <br />

In the Attachments there is my “pieTemplate.pptx” file.

I use Aspose.Slides 15.4.0.

Hi … Again,

I have played with the template file and i found out that if the chart in the Template file is a PIE Chart that i don’t can modify the Chart type.

BUT if the Chart in the Template file is a BAR Chart i can modify / change the type to PIE, RADAR and so on…

Pretty strange but helps me and the people who have the same problem

Hope that help you to found the Problem with the PIE Chart…
