The RGraph license

Creative Commons Attribution-NonCommercial 3.0 RGraph is free for non-commercial use under the Creative Commons Attribution-NonCommercial 3.0 license, meaning you just need to link to the RGraph website (eg underneath the chart) if you're using it for non-commercial purposes and there is a commercial license available if you're a commercial entity or if you're a non-commercial entity but you don't wish to link to the RGraph website. Here's some sample HTML that you can use for linking to the RGraph website:

 

 

Standard license: £99

For the majority of use cases the licensing for RGraph is very simple - there's just one per-company license which is 99. This covers use on websites, private websites (eg intranets) or in offline materials.

 

OEM license: £499

The one exception to the standard licensing is for OEM use. This allows you to include RGraph in your own software which may be used for the purposes of building websites or related materials and you would prefer your Customers not to incur any further costs as a result of using RGraph; or a similar situation where your software contains RGraph and you don't wish your users to be liable for their own RGraph license. In this case the OEM license is 499. You can use the "Buy now..." button above to purchase this license type.

OEM License terms

  1. You are granted the non-exclusive rights set forth in this document provided you agree to and comply with any and all conditions in these terms.
  2. You may develop application programs, reusable components and other software items that use the original or modified versions of the RGraph software. You may include RGraph as a part of the software that either supports or controls the software or device(s) that you make.
  3. The OEM license permits you to use RGraph as part of your own software or hardware which may or may not then be used by your own Customers to build web sites, web applications, web based software or non-web based software. As a result of using your software or hardware your Customers do not have any further responsibility to purchase their own RGraph license.
  4. The OEM license can also be the most economical way of licensing a large number of your clients. If you do have a large number of clients who use your product(s) (which may or may not be on different domains) then instead of buying a license for each Customer you can instead buy an OEM license which will cover all current and future usage. The OEM license is a one-time payment of £499.
  5. You may use the RGraph name in your promotional materials if you wish to promote your software or hardware. The RGraph name must not be used in a derogatory, defamatory or negative way or in a way that would bring RGraph into disrepute. You may not sell/resell or purport to sell/resell RGraph licenses or do anything which may cause harm to RGraph Licensing sales. The OEM license is for you and Customers who buy your products or services only.
  6. You may not sell, resell or otherwise provide RGraph as an independent piece of software. You may include RGraph as part of your own software, hardware or as part of the service(s) that you provide but you may not sell/resell RGraph or purport to sell/resell RGraph licenses

If you make an authoring tool that you wish to include RGraph with then you're free to do so.
