Open Source and Free to use

Fed up with the high cost of JavaScript charting libraries? RGraph isn't like that - it's Open Source and Free to use! No up-front payment; no recurring fees and no usage caps. You can use it as much or as little as you wish without paying anything. Just think of all the money you'll save - happy days!

Combine different types of charts

Multiple charts can be combined on a single SVG or canvas tag. This means you can combine types to create rich charts and dashboards.

Data import utilities

If your data is stored in Google Sheets, a CSV file or via AJAX then RGraph has utilities for you! They allow you to fetch data directly without storing it as a file on your web-server first.

Animations and effects

Animations and effects are available for each chart type and there's a number of CSS3 effects available that can be used with any chart.

Fully documented

From the canvas HOWTO documents to the SVG docs pages the RGraph library is fully documented. There's a large section dedicated to installation and setup to help you get up and running. Failing that you can ask support question in the support forum.
