I have created a simple presentation in Powerpoint with one basic chart (not a linked excel). When I edit the chart data in my code with aspose and save the presentation I can no longer access the data in powerpoint. Powerpoint gives me alert: “The linked file isn’t available. This error can occur if the linked file has been moved or hasn’t been saved. Embedding the data instead of linking it can help avoid this error, but the data won’t be updated automatically if it changes in the source file.”
this sounds similar to Unable to edit chart data in PowerPoint for Aspose.Slides generated chart (C# .NET) but in my case it’s aspose slides java.
Any help appreciated.
