RGraph: HTML5/Javascript charts for your website

“For reporting performance tests, we needed a reporting system that is readily available, easily accessible, produces different reports for different audiences (Management, Engineers, Scrum Masters, Product Audiences, etc) and different periods (daily, weekly, iterations, etc). After a thorough spike, RGraph was chosen as our charting library to use with HTML5 (canvas), JavaScript, CSS, jQuery and a LAMP solution stack. The library proved to be great value for money, and yes, it is extremely cheap compared to other libraries that we looked at. RGraph also has great features. For example, we could use the tooltips when we are on a line chart to get bar charts for the previous x days/weeks, etc in our reports. It also had different kinds of charts, so our design was not limited by the library. For the management reports, speed was a factor, and RGraph worked well with HTML5, returning the graphs much faster than other libraries. All in all, I am happy with our selection, price, ease of use, features, footprint, support and many others.” - Yingwani Jan Mnisi, Cisco Ireland Write a testimonial

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 Javscript, 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.
