Find out about changes in the latest release of RGraph

About

RGraph is a JavaScript charts library based on HTML5 SVG and canvas. RGraph is mature (over 17 years old) and has a wealth of features making it an ideal choice to use for showing charts on your website.

Version 7 released

Version 7 (released in August 2025) is the latest version of RGraph and brings with it a big improvement in the quality of the text that's rendered on canvas charts. This new improvement in text rendering is the major focus in this release. Read more about the new scaling feature at the link below.

New HTML datagrid

In the April 2025 release a new datagrid object was added. This makes it easy to add static or dynamic data tables to your pages. It can be used whether you use the canvas or SVG libraries or entirely standalone.

Current release: August 2025 (7.00)

This is a major version increase that only has a single significant improvement (and a few other minor tweaks) and that improvement is... greatly improved text! The new technique that's used to draw text is called scaling and you can read the documentation page describing the new scaling feature here. There's a list of points to be aware of on that page but one thing that stands out is that the coordinate space of the canvas tag has been doubled (despite the canvas tag remaining at the same width and height dimensions). This probably won't affect you if you just have a regular chart - but if you're delving into the API or doing custom drawing of your own then this is something that you'll now need to keep in mind and account for it in the coordinates that you use.

The antialiasing HOWTO document has been updated with a comparison of no antialiasing, the previous antialiasing style and the new antialias methostyle.

Remember - this update affects the canvas charts along with the drawing API objects.

The RGraph.getImage() function has been added to the canvas common library which gives you an easy way to get a data: URL that represents the canvas (ie it's an easy way to get an image). The function is documented in the API documentation.
