Change chart font style

hello

i use aspose for working with pptx. How can i change this font style?
Thank you.

and how i get a current font style?

for example if i do something like that :
destinationTextFrame.Paragraphs[0].ParagraphFormat.DefaultPortionFormat.FontHeight
i have value = NaN

Hi,


I have observed the requirements shared and like to share that Aspose.Slides allows you to access and change the value/category axis text formatting. Please visit this documentation link where by I have shared the sample code to format different chart entities including Category and Value axis. Please share, if I may help you further in this regard.

Many Thanks,
