Charts - Scatter charts - Scatter Line Chart
Documentation: scatter_line
Note: how the purple 'night lovin' line is actually 2 lines.
This goes into the <head> of the page:
<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF(
"open-flash-chart.swf", "my_chart",
"600", "400", "9.0.0", "expressInstall.swf",
{"data-file":"gallery/scatter-mixed.php"} );
</script>
This writes the chart into a div with id="my_chart",
right click and view source to see it in action,
[the tutorials have more details]
