Highcharts+Spring饼图使用实例

项目上要用到Hightcharts展示平台机器占用情况,使用这类第三方插件很方便就能实现

JSP:

<script type="text/javascript" src="<%=basePath%>/resources/thirdparty/highcharts/highcharts.js"></script>

<div id="machineRate"  title="按产品线统计机器占比" style="display:inline; width:50%;float: left"></div>

JS:

/**查看机器占比(按产品线) [email protected] 2015/8*/
function loadMachineRate(){
	var chart;
	$(document).ready(function(){
		chart = new Highcharts.Chart({
			//常规图表选项设置
            chart: {
                renderTo: 'machineRate',        //在哪个区域呈现，对应HTML中的一个元素ID
                plotBackgroundColor: null,    //绘图区的背景颜色
                plotBorderWidth: null,        //绘图区边框宽度
                plotShadow: false            //绘图区是否显示阴影
            },
            //图表的主标题
            title: {
                text: '按产品线统计机器占比'
            },
            //当鼠标经过时的提示设置
            tooltip: {
                pointFormat: '{series.name}: <b>{point.percentage}%</b>',
                percentageDecimals: 1
            },
          //每种图表类型属性设置
            plotOptions: {
                //饼状图
                pie: {
                    allowPointSelect: true,
                    cursor: 'pointer',
                    dataLabels: {
                        enabled: true,
                        color: '#000000',
                        connectorColor: '#000000',
                        formatter: function() {
                            //Highcharts.numberFormat(this.percentage,2)格式化数字，保留2位精度
                            return '<b>'+ this.point.name +'</b>: '+Highcharts.numberFormat(this.percentage,2) +' %';
                        }
                    }
                }
            },
            //图表要展现的数据
            series: [{
                type: 'pie',
                name: '机器占比'
            }]

		});
	});
	$.ajax({
		type : "GET",
		url : "machine/getStaticMachineRateByProductLine",
		success : function(data){

			//定义一个数组
	        browsers = [],
	        //迭代，把异步获取的数据放到数组中
	        $.each(data,function(i,d){
