Version 7.10 released
Version 7.10 (released in January 2026) is the latest version of RGraph and contains various updates to the code which you can see on the changelog page. There's also a big tidy up in terms of comments and a significant change to the way that the internal code is referenced which should lead to a performance improvement in effects and animations.

Demo pages fail to show code


Posted by Kim at 11:25 on Saturday 12th December 2020 [link]
theres an error in the demo pages that fails to show the code:
js console says:
Uncaught SyntaxError: Unexpected token '<' demos.js:1
bar-line-switch-effect.html:372 Uncaught ReferenceError: showSource is not defined
    at bar-line-switch-effect.html:372
navigation-top-bar.js:9 Uncaught TypeError: Cannot set property 'onclick' of null
    at navigation-top-bar.js:9

and it seems that the the demos.js file has some garbage at the top:
<br />
<b>Warning</b>: Undefined variable $lastmod in <b>/homepages/46/d548322256/htdocs/www/demos/combined.html</b> on line <b>64</b><br />

Can you do a SHIFT+refresh or CTRL+refresh (depends on your browser) to bypass the local browser cache?

I did upgrade PHP on the website recently, but if I do this then everything works as expected.
