rawdatafreq doesn't seem exist in for loop.
should try store raw data in variable, reference in series.dataname , in for loop.

function makechart(){     var rawdatafreq = [/* data array */];      $('#container').highcharts({         /* code truncated */         series: [{             "name": "rawdatafreq",             "data": rawdatafreq         }]         /* code truncated */     });      (var = 0; < rawdatafreq.length; i++) {         /* code truncated */     } }
