Aspose.Slides 21.5 Is Corrupting Charts in PPTX Files

Issues noticed are:

  1. Year labels are being lost when just loading and then saving file with Aspose.Slides 21.10 as well (latest version).
  2. We tested and verified that the issue was introduced in Aspose.Slides 20.12.
  3. The issue is not happening in Aspose.Slides 20.11 and lower.
  4. You can check the sample app or just check “BEFORE” and “AFTER” files in “bin” folder.

You can access the above mentioned file from our public drive https://files.axiomint.com/external/e000dac8c18d21d5c7dccf8bc15c50b21509038d81aa24ea9b0d6d165648f31b

In the above folder you will see the sample file [ChartYearLabelIssue.pptx] and the C# solution [AsposePPTXChartCorruption2.zip].

You can reproduce the issue by:
a. Running the sample solution and then checking “BEFORE” and “AFTER” files in the “bin” folder.
b. Testing the sample files attached. For that, you just need to load it by Aspose.Slides library and then save it back.

Thank you for the issue description.
