Creating an editable Word chart programmatically with docx4j (v11.4.9)

[raggamozga-del]

Hello,

I am using docx4j version 11.4.9 to generate Word documents programmatically.

I would like to create a chart that remains editable in Microsoft Word, similar to charts inserted directly via Insert → Chart in Word.

Specifically, I need to generate a chart that:

• appears as a native Word chart (DrawingML chart),
• contains editable data,
• allows the user to open Edit Data in Word (which opens the embedded Excel sheet) and modify the chart values.

I have attached a DOCX file containing an example chart which demonstrates the desired result.

My goal is to generate such a chart programmatically using docx4j.

Questions

1. Is it possible to create such an editable chart from scratch using the docx4j API?

2. If yes, could you provide an example or point to the relevant classes/APIs that should be used?

3. Is the recommended approach:

   • creating the chart structure manually (DrawingML + embedded XLSX), or
   • using a chart template and updating its data?

I reviewed the documentation and some chart-related classes in docx4j, but I couldn't find a clear example demonstrating how to create a Word chart with embedded editable data programmatically.

Any guidance or code examples would be greatly appreciated.
