We need to create a document that contains Excel charts. I am able to open a work document not using Aspose, and copy the chart into it, but I am not seeing how to do this in Aspose Words.
You can first convert an Excel chart to Image by using Aspose.Cells API and then insert this chart image into Word document by using Aspose.Words API.
Document doc = new Document("input.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd(); // or move cursor to any Node
builder.InsertImage("image.bmp");
doc.Save("output.docx");
doc.Save("output.pdf");
Hope, this helps.
