Saving Excel chart with at lease two data series labels with colored font


Saving an Excel chart with multiple data series and setting the font color to something other than automatic for the labels of at least two series will throw ArgumentOutOfRangeException.

In order to reproduce the issue run the code below on the attached file.

var wb = new Workbook(@“C:\Sample Object.xlsx”);
wb.Save(“c:\Sample Object Result.xlsx”, Aspose.Cells.SaveFormat.Xlsx);

Thanks for the sample file and sharing the sample code.

After an initial test, I found the exception when re-saving the template file you attached as you have mentioned:
“Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index”
