Generate Pdf from Excel

I have an excel document that have a chart, when I generate Pdf, I got a pdf document but dont have any chart image.
Please show me the way to get chart image from excel document and insert to pdf document, or any solution to generate pdf from excel with chart ?

thanks.

Now xls2pdf feature is implemented in this way:

1. Aspose.Excel exports xml file that can be recognized by Aspose.Pdf
2. Aspose.Pdf imports the xml file and generates the pdf file

Currently charts, images and other drawing objects are not supported within this conversion. In the future release, we will investigate to convert images. However, charts and other drawing objects will not be support in a short time because of its complexity.
