JpGraph Professional Version
If you plan on using JpGraph in a commercial context you will need to acquire the professional license. Commercial use is for example if you use JpGraph on a site to provide a service for paying customers or for example if you are using JpGraph in an intranet to provide support for internal business processes, i.e. in benefit for a commercial company.
In short, if you use JpGraph where you have an economic advantage (either through paying customers or improving internal business processes) this most likely falls under commercial use.
