在数据统计和分析业务中，有时会遇到客户需要在一个图表中将柱状图、饼状图、曲线图的都体现出来，即可以从柱状图中看出具体数据、又能从曲线图中看出变化趋势，还能从饼状图中看出各部分数据比重。Highcharts可以轻松实现三图合一的效果。
代码如下:
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: ‘container’,
defaultSeriesType: ‘area’
},
title: {
text: ‘Historic and Estimated Worldwide Population Growth by Region’
},
subtitle: {
text: ‘Source: Wikipedia.org’
},
xAxis: {
categories: [‘1750’, ‘1800’, ‘1850’, ‘1900’, ‘1950’, ‘1999’, ‘2050’],
tickmarkPlacement: ‘on’,
title: {
enabled: false
}
},
yAxis: {
title: {
text: ‘Billions’
},
labels: {
formatter: function() {
return this.value / 1000;
}
}
},
tooltip: {
formatter: function() {
return ”+
this.x +’: ‘+ Highcharts.numberFormat(this.y, 0, ‘,’) +’ millions’;
}
},
plotOptions: {
area: {
stacking: ‘normal’,
lineColor: ‘#666666’,
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: ‘#666666’
}
}
},
series: [{
name: ‘Asia’,
data: [502, 635, 809, 947, 1402, 3634, 5268]
}, {
name: ‘Africa’,
data: [106, 107, 111, 133, 221, 767, 1766]
}, {
name: ‘Europe’,
data: [163, 203, 276, 408, 547, 729, 628]
}, {
name: ‘America’,
data: [18, 31, 54, 156, 339, 818, 1201]
}, {
name: ‘Oceania’,
data: [2, 2, 2, 6, 13, 30, 46]
}]
});
});
