highchats与php组合生成动态统计图

series: [{            type: 'pie',            name: 'Browser share',            data: [                ['Firefox',   45.0],                ['IE',       26.8],                {                    name: 'Chrome',                    y: 12.8,                    sliced: true,                    selected: true                },                ['Safari',    8.5],                ['Opera',     6.2],                ['Others',   0.7]            ]        }]

主要看这段：

{name: 'Chrome',y: 12.8,sliced: true,selected: true}

											'上海', 'y'=>28.2),				array('name'=>'北京', 'y'=>48.2),				array('name'=>'广东', 'y'=>18.2),		);	$data = json_encode($b);	echo($data);}?>	

输出：{"2":{"name":"lo","data":[0,0]},"3":{"name":"eth0","data":[0.40377,0.00353]}}js调用:

series: [						ds[2], ds[3]					]
