Hi Team,
I have a requirement where I need to show an axis data value with a plus (+) in PPT (bar chart) provided below, need to show 20+, I don’t need to format the entire X axis in the chart. I have tried number formatting however it applies to all the data labels on X axis.

using Aspose.slides.NET (24.1.0)
using Aspose.slides.NET6.CrossPlatform (24.6.0)

Any way of achieving this?

Thanks in advance

@Ghanu86,
Thank you for posting the question.

Unfortunately, PowerPoint documents do not support such a feature. A single axis data label cannot be customized.
