I cannot figure out how to label my objects in Aspose.PDF.Drawing.Graph.
In the old version I could add GraphNotes to a graph.
B.T.W. - I don’t know if I chose the correct product family, none of them make sense, especially the ones in chinese.
Could you please clarify what specific functionality you are looking for regarding labeling objects in Aspose.PDF.Drawing.Graph? Additionally, which version of Aspose.PDF are you currently using?
Aspose.Pdf version 22.1.0
I used to be able to produce this with Aspose.Pdf.Generator. See all the labels in the drawing.

Could you please share the sample code with us that you have been using with Aspose.Pdf.Generator API?
The code will not run without data connections. I will have to make something up to demonstrate.
Here is a quick demonstration of a graph with shapes and labels.
