The RGraph license

RGraph is free to use for non-commercial entities and there is a non-free commercial license available for commercial entities who wish to use RGraph. The commercial license is described below.

 

An overview of the licensing terms

A simple and straight-forward overview of the licensing is that for commercial use there is a single licensing fee of £79 (GBP) (which is approximately $120 USD) whilst for non-commercial use (eg personal, government, charity, educational etc) it's free to use assuming that you link to www.rgraph.net on your website.

 

Commercial usage

Commercial usage covers commercial entities for their websites (either internal or external) or in software that they produce. If your organisation generates profit then a commercial license 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

You may alter the RGraph code to suit your particular needs. Also, if you're covered by the non-commercial license, however you don't wish to link to the RGraph website then buying a commercial license means that you dont have to.

 

Commercial license FAQs

 


Do I need to buy a commercial license?
For commercial/business use, then yes - you need a license to use RGraph.

 


How many licenses do I need?
Regardless of how much you use RGraph in your organisation or in the software you make, you are only required to buy one RGraph license. If you're a freelance web developer/designer then each client would need their own license but there are discounts available for buying in bulk, and the dicount increases the more licenses you buy.

 


How much is a license?
An RGraph license costs £79 (UK pounds). That's a little over $120 (US dollars) at the time of writing.

 


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 you can usually be accommodated assuming that you're a license holder. Please contact support first to discuss your needs. If it's not too specific to you then it can be added to the main RGraph software. If it is then it can be added to your specific copy of RGraph. You can contact support with support@rgraph.net

 


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?
In this situation each client would need a separate license for themselves. They can then use RGraph as much as they wish. 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:

  1. The license you choose for your project may be incompatible with commercial software. The GPL is a prime example of this. Read your license carefully to find out whether you can use commercial software with it.
  2. If you don't want any commercial users of your software to be liable for an RGraph license you can buy an RGraph license to cover your software specifically.
 


Is there a discount for buying licenses in bulk?
Yes there's a discount available if you wish to buy 5, 10 or 15 licenses (you're a web designer for example wishing to license your clients). You can buy the volume licenses here.

 


What if I make a website authoring tool?
If you make a website authoring tool (eg Frontpage, Dreamweaver etc) then you can include RGraph with your software but each and every commercial Customer who makes use of it would be liable to buy their own full-price license.

 


Do I need to provide a backlink?
Commercial license holders do not need to provide a backlink to the RGraph website.

 


Can you send me an invoice?
Of course, simply go here: http://www.rgraph.net/invoice.html, enter your email address and you'll be sent an invoice that you can use for tax purposes.

 

Non-commercial free usage

RGraph can be used free-of-charge by non-commercial entities 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:

Sample HTML for a link is:

<a href="http://www.rgraph.net" target="_blank">
    Charts made with RGraph: HTML5 Javascript charts library
</a>

If you would prefer not to link to the RGraph website, then you can buy an RGraph commercial license and you won't need to. You may alter the RGraph code to suit your particular needs.

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!
