I am trying to open an existing powerpoint presentation that contains charts, and need to access and manipulate the data associated with the chart.
(I have seen the code to create a chart from scratch in a presentation using aspose.slides, however I need to open and manipulate the existing charts that are not necessarily created using aspose.)
I see that an existing chart is represented by an instance of Chart or ChartEx. My question is how we can get the worksheet and edit its data.
Thanks very much,
Thanks for considering Aspose.Slides.
I regret to inform you that Aspose.Slides for .NET does not support creating charts in it. However, you may create your own charts in our other product, Aspose.Cells and then embedding the generated chart in presentation using Aspose.Slides either as an image or as on OLE frame. Regretfully you may not update the chart or data associated with it using Aspose.Slides. Please visit this link for demo application.
Thanks and Regards,
