    You can try using JasperReports. They are a bit heavy, but working good.

    Copy the OutputStream from your chosen writeChartAs*() method in ChartUtilities to the InputStream used to create a PDXObjectImage in AddImageToPDF. A typical copyStream() implementation is shown here.

    Addendum: Alternatively, use piped streams to copy from output to input, as shown here and here.
