JavaScript を使ったプログラミングは初めてで、HighCharts チャートの実装に問題があります。私が使用している API はマークイット ( https://github.com/markitondemand/DataApis/blob/master/MarkitTimeseriesServiceSample.js ) で、このページhttp://dev.markitondemand.com/の途中に示されているグラフを生成します。
ここで、このフィドルに示されている js の代わりにその js スクリプトを追加する必要があると考えました ( http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/ samples/highcharts/demo/line-basic/ ) ですが、機能していないようです。
実際に置きたい場所を割り当てていないためかもしれませんが、100％確信が持てません。
私のコードについては以下を参照してください。
