Sorry, no offence. I was just asking. This would mean that anyone who will be using your scripts, and wants to use the charting features, will have to buy ChartDirector, right?
The URL telling me you cannot use it for free is http://www.advsofteng.com/purchase.html
. It says:
Developer license: "License for using ChartDirector on one computer/server running Windows, Linux or FreeBSD, for development, production or any other purpose."
As the RFXChart scripts and binaries come including the ChartDirector functionality I guess Paul (Sooty) has a redistribute license;-)
