I've been looking for a javascript library like highcharts or rgraph which contains the ability to add a report filter. Does anyone know if there is one?
If 'report filtering' = show/hide certain data from the chart. Check this out. i haven't used it myself but looks good: http://code.shutterstock.com/rickshaw/
Also this one looks great too: http://nvd3.org - also powered by the awesome d3.js library
