“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

Documentation and HTML5 examples

Free to use!

RGraph is free to use on non-commercial websites such as personal blogs, educational, charity or government websites - you don't need to buy a license. Go here for details about a commercial license.


Many different styles of charts

RGraph supports 20+ chart types, including Bar charts, Line charts and Pie charts, with many having variations available, such as the Line chart with the X axis in the center. Examples of all the charts are available from the examples page and there are more in the documentation.

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 combine charts such as the Line and Bar chart and as of the next release you'll be able to combine more types of charts with more dynamic features.

All charts and features are documented with examples and code that you can use. The HOWTO guides walk you through doing some 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. The API is documented and there is also a bare-bones implementation available if you want to extend RGraph and make your own charts.

Fast support

Support is available by email (support@rgraph.net) with responses typically taking a matter of hours or less.

Javascript dashboard solutions

RGraph supports a variety of Progress Bars and Meters which allow you to create rich dashboards for monitoring your servers or applications. Types of meters include:


Most of the meters can be animated like the example on the right.


Multiple chart support

With the current stable release charts can be combined but when you start adding dynamic features things start to get complicated. As of the next stable release, thanks to something called the Object Registry, you'll be able to combine more charts with dynamic features such as tooltips or effects. You can see examples of this by looking at the test area. Note: This is a development area and things may not work correctly. It is intended as a preview only!

At the time of writing there's lots to do so the next stable release will be at the end of March at the earliest, possibly later.
