1. 饼状图(Pie Chart)示例:

<div id="container" style="height: 400px"></div>
<script type="http://.....jquery-1.9.1.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
<script type="text/javascript">
$(function () {
$('#container').highcharts({
chart: {
type: 'pie',
plotBackgroundColor: 'lightgrey',
plotBorderWidth: 2,
plotShadow: true
},
title: {
text: 'Pie chart'
},
colors: ['#7cb5ec','#434348','#90ed7d', 'grey'],
credits: {
text: 'Designed by IT Dept.'
},
tooltip: {
pointFormat: '{point.name}:<b>{point.y}</b>',
headerFormat: ''
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true
},
showInLegend: true
}
},
series: [{
name: 'Sales',
data: [['A',29.9], ['B',71.5], ['C',106.4], ['D',129.2]]
}]
});
});
</script>

效果:

2. 对于饼状图(Pie Chart),由于数据格式的特殊性,在tooltip中可以使用{point.name}来获取数据的Key值,使用{point.y}来获取数据的Value值;

饼状图(Pie Chart)的数据格式:

series: [{
name: 'Sales',
data: [['A',29.9], ['B',71.5], ['C',106.4], ['D',129.2]]
}]

获取Json格式数据的Key和Value:

tooltip: {
pointFormat: '{point.name}:<b>{point.y}</b>',
       headerFormat: ''
},

效果图:

2. 在饼状图的toolTip中,point.key在headerFormat中可以显示为Key值,但在pointFormat中显示为该key的序号(从0开始);
