RGraph is a HTML5 Javascript charts library that supports over 20 different types of charts. Using the new HTML5 canvas tag, RGraph creates these Javascript charts in the web browser, meaning quicker pages and less web server load. Using RGraph is an easy way of speeding up your website.
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.
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.
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.
Support is available by email (support@rgraph.net) with responses typically taking a matter of hours or less.
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.
