Hi Asnidzal,
I suspect the quickest solution will be to use IMPORT JAVA, and link to a Java library to draw the chart and save as an image for inclusion in your report.
Please get in contact with your local support center,
support@4js.com.au to discuss this further. Also FYI some of that team will be in KL later this month.

I (with a little help from Alex and Rene in places) put together an example showing how you can use IMPORT JAVA to utilise the JFreeChart libraries that are shipped inside GRW to create an image containing a SpiderWeb chart. Source is available here
https://github.com/FourjsGenero/fgl_jfreechart. This technique should be able to be extended to any of the other chart types available in the JFreeChart library.
Mac users, make sure you read the README for the command line argument required.
