if adding constant series data like

chart.addseries({ name: 'rainfall11', type: 'column', color: '#08f', data:[100, 200, 300, 400, 100, 200] });

some graph displaying. while coming dynamic data doesn't show up. using date.utc function display the

i sending json data through variable, series_data function renderchart result of ajax function . sample json result this.

{"ferrari april 2013":[{"date":"2013-06-05","month":"june-2013","count":"1.00"},{"date":"2013-06-08","month":"june-2013","count":"1.00"},{"date":"2013-06-15","month":"june-2013","count":"1.00"},{"date":"2013-06-16","month":"june-2013","count":"1.00"}],"ferrari may 2013":[{"date":"2013-06-05","month":"june-2013","count":"1.00"},{"date":"2013-06-07","month":"june-2013","count":"1.00"},{"date":"2013-06-08","month":"june-2013","count":"2.00"},{"date":"2013-06-09","month":"june-2013","count":"3.00"}],"ferrari march 2013":[{"date":"2013-06-07","month":"june-2013","count":"1.00"}],"ferrari june 2013":[{"date":"2013-06-10","month":"june-2013","count":"1.00"},{"date":"2013-06-11","month":"june-2013","count":"1.00"},{"date":"2013-06-12","month":"june-2013","count":"1.00"},{"date":"2013-06-13","month":"june-2013","count":"3.00"},{"date":"2013-06-14","month":"june-2013","count":"2.00"},{"date":"2013-06-16","month":"june-2013","count":"4.00"},{"date":"2013-06-17","month":"june-2013","count":"1.00"},{"date":"2013-06-18","month":"june-2013","count":"2.00"}],"ferrari february 2013":[{"date":"2013-06-11","month":"june-2013","count":"1.00"},{"date":"2013-06-18","month":"june-2013","count":"1.00"}]}

the problem comes in date.utc part guess . because when console.log() showing nan .

please fix issue.

i excepting result this.

hope works!
