我正在尝试完成此处显示的内容
http://jsfiddle.net/r7UsK/
基本上我想要一个低于 0 标记的红色背景，以使负值更加突出。
这是我当前的版本

我做错了什么？
JS代码
chartItems = new Array();
chartItems.push(["Civilian Afterburner","2013-05-20 07:05:03","5841223.56"]);
chartItems.push(["Civilian Afterburner","2013-05-20 22:00:59","5841321.12"]);
chartItems.push(["Civilian Afterburner","2013-05-21 22:00:31","5841289.08"]);
chartItems.push(["Civilian Afterburner","2013-05-22 22:01:08","5841566.46"]);
<Data Sniped>
sorted = {};
$.each(chartItems, function(){
if(sorted[this[0]] == undefined) sorted[this[0]] = new Array();
sorted[this[0]].push([Date.parse(this[1]), parseFloat(this[2])]);
})
series = []
$.each(sorted, function(i){
series.push({
type: 'spline',
name: i,
data: this,
marker: {
radius: 4
}
})
})
$('#container').highcharts({
