MIT License

RGraph is completely free to use, licensed using the MIT license. You don't have to pay me anything to use it. Any donations are always very welcome of course! It doesn't have to be a large donation - even if you can only spare £9 it's appreciated. Thanks.

Donations of £19 or more can have the name linked to a website (see the donor list below). I'll email you to see where you'd like the link pointing to. I won't be linking to any dodgy or pornographic sites though!

If you have any trouble sending your donation then please let me know. You can use the support forum to get in touch

History of RGraph

RGraph started out in 2008 as a commercial endeavour - licensed using the Creative Commons BY_NC license. It was like this for a while but was then switched to an Open Source license and that's what it is now. 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!
