Highcharts - Pie Chart

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>
View Code

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);
