Support the development of RGraph
RGraph uses the MIT license. That means that you can do whatever you want with it and use it as much or as little as you please. If you want to donate to help with the ongoing development of RGraph then there are PayPal buttons that you can use below. All donations are very much appreciated!
RGraph is completely free to use, licensed using the MIT license. You don't have to pay anything to use it. Any contributions to the project are always very welcome of course! It doesn't have to be a large amount - even if you can only spare £5 it's appreciated. Thanks.
If you have any trouble sending your contribution then please let me know. You can send me a message via the support page.
RGraph is Free and Open Source Software
RGraph was originally started as a commercial project - licensed using the Creative Commons BY_NC license and it was like this for a while but was then switched to an Open Source license and that's what it is now, and therefore it's truly Free and Open Source Software (FOSS).
As a result you don't have to pay me for using it, buy me a gift or take me out for a drink. Use it; don't use it; it's up to you! You can read more about me on the About page...
If you can't donate then I'd be very happy if you could submit a testimonial - which you can do here.
The MIT license is well known as an Open Source license and means that you can use RGraph for any purpose you wish - non-commercial or commercial.
You can include it your own software, modify it and distribute it without asking for permission or paying any fees.
There is nothing that the end user needs to do or buy and there's no requirement for you to share your changes should you make any. Basically: You can do what you like with it!
