RGraph: HTML5/Javascript charts for your website

“I had a redesign of my Weather Station web-page coming up, and decided to migrate Adobe Flash to a more future-proof solution, HTML5. I discovered I had a steep learning curve ahead of me, and started looking for an easier way out. I discovered RGraph and gave it a try, and after I modified the code to suit my needs I got a chart that I liked.Following this, I registered to buy a license and sent my chart to RGraph support asking for a library script that generates the chart I wanted. To my big surprise, although it was a Saturday, I got an answer within the hour. Short and simple, you will get what you require! This library saves me a lot of time. Well documented libraries mean that future maintenance is really easy.

Conclusion: I got my HTML5 code done very fast with minimal effort and very good support!” - Johnny Wik, web developer Write a testimonial for the RGraph website

Build faster websites using Javascript powered charts and HTML5

RGraph is a charts library that uses Javascript and HTML5 to draw and supports over twenty different types of charts. Using the new HTML5 canvas tag, RGraph creates these charts inside the web browser using Javascript, meaning quicker pages and less web server load. This leads to smaller page sizes, lower costs and faster websites - everybody wins!

Free to use!

RGraph is free to use on non-commercial websites such as personal blogs, educational, or charity sites - you don't need to buy a license - only link to the RGraph website on your own site. Go here for details about a commercial and government license.

Feature packed and fully documented

As you'll see from the documentation RGraph has lots of features, such as tooltips, visual effects, zooming, context menus, interactive adjusting and resizing to name a few. You can also combine different types of charts (see the examples for more).

All charts and features are documented with examples and code that you can use. The HOWTO guides walk you through doing common tasks step-by-step with more example code.

The full source is included in the download and you're free to make changes to suit your needs. The API is documented and there is also a bare-bones implementation available if you want to extend RGraph and make your own charts.
