any order of placing js files wrong..?

yes. your highcharts setup code needs to come after the script tags that loads the highcharts library.

<script type="text/javascript" src="js/highcharts1/highcharts-2.3.5.js"></script>
<script type="text/javascript" src="js/highcharts1/modules/exporting-2.3.5.js"></script>
<script>
    function buildhighcharts(){ ... }
</script>
