RGraph is a JavaScript charts library based on
HTML5 SVG and canvas. RGraph is mature (over 18 years
old) and has a wealth of features making it an ideal
choice to use for showing charts on your website.
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.
In the April 2025 (v6.21) 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.
Get the latest version of RGraph (version 7.10, 18th January 2026) from
the download page. You can read the changelog here. There's also older versions available,
minified files and links to cdnjs.com hosted libraries.
Using semi-colons after functions can lead to better
minified, and thus smaller, files. Why? Because a function
expression,
like other expressions (and also function declarations),
can have other expressions after it - just like your average
joe javascript expression. So this is
perfectly legal:
var myFunc=function(a){alert(a);};var myVar=48;
When it's not minified it may look like this:
var myFunc = function (a)
{
alert(a);
};
var myVar = 48;
But without the semi-colon it would look like this:
var myFunc=function(a){alert(a);}var myVar=48;
Which is not valid.
Function declarations are subtly different - they don't
need semi-colons after the closing brace (or often a space
too). For example, this would be fine:
function myFunc(a){alert(a);} var myVar=48;
How significant is the difference?
Not much. A byte or two. But as the UK grocery store Tesco says... "Every little helps...". Though if you're using
compression it may make no difference at all. Still - now you know when they're necessary so it may save you
some a lot of confusion.
