RGraph is free for non-commercial use and there is a non-free license available for commercial and government use which operates on a per-domain basis. The commercial license is described below.
A straight-forward overview of the licensing is that for commercial and government use there is a per-domain licensing fee of £99 (GBP) (which is approximately $155 USD) whilst for non-commercial use (eg personal, charity, educational etc) it's free to use - just link to www.rgraph.net on your website.
Commercial and government use covers commercial entities and government departments/agencies (eg councils or contractors working for a government department/agency) for their websites (either internal or external) or in software that they produce. The license is issued on a per-domain basis - so foo.com and bar.com would each need their own license. You can then use RGraph on as many sub-domains as you wish - so a.foo.com and b.foo.com would only require one license.
If your use of RGraph is for an offline application, each seperate application would need its own license, regardless of how many users or installations that the application has or on how many computers that it's installed on.
If your organisation generates profit or can be thought of as a government or government contractor then the commercial licensing is most appropriate. There are some legal terms and FAQs below that should help to answer any questions that you may have, but if they don't then you can email your question to: support@rgraph.net
After completion of either Google Checkout or Paypal payment you are granted an RGraph commercial license for the domain that you specify during checkout. You will be sent the license details via email.
Example uses are:
Do I need to buy a commercial/goverment license?
For commercial, business or government use, then yes - you need a license to use RGraph. If your website doesn't sell
anything but can be classed as commercial (eg a company website) or government (eg a council website)
then that would still require an RGraph license.
How many licenses do I need?
RGraph is licensed on a per-domain basis so each domain would need its own license. Examples of domains are:
rgraph.net, bbc.co.uk, google.com etc. If you have several
domains that you want to license there are discounts available for buying in bulk,
and the discount increases with the number of licenses that you buy.
How much is a license?
A single per-domain RGraph license costs £99 (UK pounds). That's a little over $155 (US dollars) at
the time of writing.
Is the fee recurring or a single payment?
The license fee is a per-domain single payment and is not recurring.
Where can I buy an RGraph license?
The only place you can buy an RGraph license is the RGraph website using the "Buy now..." buttons at the top of this page.
How much does support cost?
Support is free and there is no time limit or restrictions on it. You can send an email to:
support@rgraph.net
What if I need something that's not part of RGraph?
If there's a feature that you need that's not part of RGraph then please get in touch with
support@rgraph.net.
Requests can usually be accommodated assuming that
you're a license holder. If it's not too specific
then it can be added to the main RGraph software. If it is then it can be added to your specific copy of RGraph.
What does the license cover?
The RGraph license covers RGraph as a whole. Excepting ExCanvas, all code that you find in the RGraph archive is
covered by the RGraph license.
What if I'm a web designer or developer?
As RGraph is licensed on a per-domain model each domain would require it's own license. Commonly this translates to
one RGraph license per client. The client can then use it as much as they wish on that particular domain.
If you prefer to buy in bulk - discounts are available, and the dicount increases the
more licenses you buy.
Can I include RGraph in an Open Source project?
You're not prohibited from using RGraph in Open source projects, however you need to be aware of two things:
RGraph can be used free-of-charge by non-commercial entities (eg personal, charity, educational etc) who wish to use it either on an internal or external website or in software that they make assuming that you link back to the RGraph website. Examples of non-commercial entities include:

If you're covered by the free license but want to make a donation to help keep RGraph going then they're all gratefully received. You can use PayPal button on the left to send it. Thanks!
