直接上代码

   <script>
    $(function () {
    $('#container').highcharts({
        title: {
            text: "{$data.title}",
            x: -20 //center

        },
        yAxis: {
            title: {

            plotLines: [{

                width: 1,
                color: "{$data['yAxis']['plotLines']}"
            }]
        },
        tooltip: {

        },
        legend: {
            layout: 'vertical',
            align: 'right',
            verticalAlign: 'middle',
            borderWidth: 0
        },
        series: [{
            name: "{$data['series']['name']}",
            data: {$data['series']['data']}

    });
});
</script>
</head>
<body>
  <div id="container" style="min-width:700px;height:400px"></div>
</body>
</html>

下面是controller的部分代码

$product_info = M('product_info')->where($where)->getField('create_time,price');//生成create_time为键,price为值的数组
$info = M('product_info')->where(array("sku"=>$where["sku"]))->find();
       $create_time = array_keys($product_info);//取得数组键
       $price = array_values($product_info);//取得值
		$title = $info['name'];
		$subtitle = $info['mall_name'];
		$data = array(
			'title'=>$title,
			'subtitle'=>'来源:'.$subtitle,
			'categories'=>json_encode($create_time),
			'yAxis'=>array('title'=>'人民币(元)','plotLines'=>'#808080'),
			'tooltip'=>'(元)',
			'legend'=>'',
			'series'=>array('name'=>$title,'data'=>str_replace("\"", "",json_encode($price))),//生成json数据后,再去除其"
		);
		
		$this->assign('data',$data);
