A Line chart in blue surrounded by a black box. The box is added after the main drawing by using the ondraw custom RGraph event.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.line.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
window.onload = function ()
{
var line = new RGraph.Line({
id: 'cvs',
data: [28,21,26,32,35,36,39,45,47,51,55,74,85],
options: {
labels: ['1950','\n1955','1960','\n1965','1970','\n1975','1980','\n1985','1990','\n1995','2000','\n2005','2010'],

}).on('draw',function (obj)
{
RGraph.path2(
obj.context,
['lw', 1, 'lj', 'miter', 'sr', 45,10,550.01,195] // The .01 is to get around a (possibly now fixed) Chrome oddity
);
})
.draw();
};
</script>
