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:
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.
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.
Do I need to buy a commercial license?

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 the RGraph support team. Assuming that you're an RGraph license holder and 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?
What if I make an authoring tool (or similar) that I wish to include RGraph with? (OEM licensing)
If you make an authoring tool that you wish to include RGraph with then you're free to do so. Keep in mind though that any commercial users who make use of RGraph will become liable for their own RGraph license. If you don't wish for this to happen then you can instead opt for an RGraph OEM license for your software. This will mean that you and your softwares users can use RGraph and not have to worry about RGraph licensing. You can use the button above to buy the OEM license.
Do I need to provide a backlink?
Commercial license holders do not need to provide a backlink to the RGraph website. If you're using RGraph under the free license then you have to provide a backlink to the RGraph website in a recognised position on your website (eg underneath the chart). If you don't wish to do this then you need to buy an RGraph commercial license.
