以下实例演示了异步加载数据曲线图表。这边我们通过 jQuery.getJSON() 方法从异步加载 csv 文件：
我们在前面的章节已经了解了 Highcharts 配置语法。接下来让我们来看个完整实例：
异步加载数据需要引入以下js 文件：
<script src="http://code.highcharts.com/modules/data.js"></script>配置
以每周为间隔设置 X 轴：
var xAxis = {
tickInterval: 7 * 24 * 3600 * 1000, // 一周
tickWidth: 0,
gridLineWidth: 1,
labels: {
align: 'left',
x: 3,
y: -3
}
};
以每周为间隔设置 Y 轴：
配置两个 Y 轴：
var yAxis = [{ // 左边 Y 轴
title: {
text: null
},
labels: {
align: 'left',
x: 3,
y: 16,
format: '{value:.,0f}'
},
showFirstLabel: false
},{ // 右边 Y 轴
linkedTo: 0,
gridLineWidth: 0,
opposite: true,
title: {
text: null
},
labels: {
align: 'right',
x: -3,
y: 16,
format: '{value:.,0f}'
},
showFirstLabel: false
}
];
plotOptions
plotOptions用于设置图表中的数据点相关属性。
var plotOptions = {
series: {
cursor: 'pointer',
point: {
events: {
click: function (e) {
hs.htmlExpand(null, {
pageOrigin: {
x: e.pageX || e.clientX,
y: e.pageY || e.clientY
},
headingText: this.series.name,
maincontentText: Highcharts.dateFormat('%A, %b %e, %Y', this.x)
+ ':<br/> ' + this.y + ' visits',
width: 200
});
}
}
},
marker: {
lineWidth: 1
}
}
}
