if 1 got idea please update code jsfidle.actuallu im doing in jsp web application in code in single line graph works perfect in mulple line thier erro

it doesn't work, because highcharts uses timestamps (time in milliseconds), dates "2013-06-27 20:28:04" incorrect. "valueint":40" have quate. in case when have push object, need have y parameter value, instead of custom name.
