Chart Elements text frames not accessible (C# .NET)

I am trying to underline or highlight legend and axes labels in chart but the change is not reflected.

chart.Legend.TextFormat.PortionFormat.FontUnderline = TextUnderlineType.Heavy

It does not work for GetThumbnail(). Exported slide, however, is updated.

Moreover, there are text manipulation options specific to Text Frames that I need to access for Legend and Axis labels. Is there a way to do that?

Thanks

@ctolap,

I have observed the issue statement shared by you and have not been able to understand that completely. Can you please share the working sample code along with source file and desired output file that you want to get using Aspose.Slides. Please also provide the obtained output as well. I also request you to please also try using Aspose.Slides for .NET 20.2 on your end as well.

Add a Column Chart to a slide.
Underline the Vertical Axis text.
Get slide thumbnail and save as image.
-> Text is not underlined in Image.
-> On saving presentation, PowerPoint slide has underlined text

Reproduced in 20.2

Text is not underlined in your sample thumbnail and presentation.
Please underline the text and check thumbnail and presentation. You will see the issue.

Please check the snapshot of presentation opened in PowerPoint and generated thumbnail. They are identification.
