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.
New datagrid in v6.21
In version 6.21 a new datagrid object has been 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.

Written by Richard Heyes, RGraph author, on 6th February 2022
I realised recently that a demo that I showed a screenshot
of on this blog, albeit some time ago, wasn't in the
download archive. So I've remedied this and the new demo
is called
demos/bar-grouped-purple.html
(it'll be
in the next release). Here's an example of it in case
you're curious. The source code of the chart is as follows:
<script> labels = [ '0 to 4','5 to 9','10 to 14','15 to 19','20 to 24','25 to 29','30 to 34', '35 to 39','40 to 44','45 to 49','50 to 54','55 to 59','60 to 64', '65 to 69','70 to 74','75 to 79','80 to 84','85 to 89','90+' ]; myData = [ [750,650],[850,800],[900,850],[1500,2800],[4000,7000], [6300,11500],[7000,11200],[6800,9800],[6800,9500], [7500,11200],[8500,12300],[8500,11000],[7500,7800], [6050,4500],[6900,5000],[8000,6400],[9000,8900], [8000,10000],[5900,11850] ]; new RGraph.Bar({ id: 'cvs', data: myData, options: { title: 'A demo of the new style of tooltips', titleSize: 16, titleBold: true, tooltips: '%{global:labels[%{group}]} %{key}', tooltipsFormattedKeyColorsCss: { border: '1px solid #ccc' }, tooltipsFormattedKeyLabels: ['Male','Female'], tooltipsCss:{ textAlign: 'left' }, tooltipsOffsety: -5, colors: ['#5C1955','#62A3B3'], marginBottom: 75, marginLeft: 75, xaxis: false, yaxis: false, xaxisLabels: labels, xaxisLabelsAngle: 45, xaxisLabelsOffsety: 5, yaxisScaleMax: 15000, backgroundGridVlines: false } }).draw(); </script>
