ECharts添加点击事件（基于饼图）：

var option = {    ...}myChart.setOption(option);myChart.on('click', function eConsole(param) { //添加点击事件 ，param输出被点击对象，包含被点击元素许多信息    var name = param.name;    location.href = 'chuchai/work-online.html#' + name;});复制代码

修改label文本类型（显示value的值）：

option = {	title: {		show: false,		subtext: tit,		x: 'right'		},	tooltip: {		trigger: 'item',		formatter: "{a} 
{b} : {c} ({d}%)"		},	legend: {		orient: 'vertical',		left: 'right',		top: 'bottom'	        data: ['直接访问', '邮件营销', '联盟广告', '视频广告', '搜索引擎']	        },	color: ['#3aa1ff', '#36cbcb', '#4ecb73', '#fbd437', '#f2637b', '#975fe5', '#5254cf', '#435188'],	series: [{		name: '',		type: 'pie',		radius: '88%',		center: ['30%', '50%'],		data: da,		label: { //饼图图形上的文本标签		        normal: {			        show: true,			        position: 'inner', //标签的位置			        textStyle: {			                    fontWeight: 300,			                    fontSize: 14 //文字的字体大小			                    },			        formatter: '{c}'			        }			},		 itemStyle: {			emphasis: {			            shadowBlur: 10,			            shadowOffsetX: 0,			            shadowColor: 'rgba(0, 0, 0, 0.5)'			            }			}		}]	};复制代码

可惜没有找到调整label文本位置的配置项。

dataset的使用：

$.get('data/asset/data/life-expectancy-table.json', function (data) {    var sizeValue = '57%';    var symbolSize = 2.5;    option = {        legend: {},        tooltip: {},        toolbox: {            left: 'center',            feature: {                dataZoom: {}            }        },        grid: [            {
    right: sizeValue, bottom: sizeValue},            {
    left: sizeValue, bottom: sizeValue},            {
    right: sizeValue, top: sizeValue},            {
    left: sizeValue, top: sizeValue}        ],        xAxis: [            {
    type: 'value', gridIndex: 0, name: 'Income', axisLabel: {
    rotate: 50, interval: 0}},            {
    type: 'category', gridIndex: 1, name: 'Country', boundaryGap: false, axisLabel: {
    rotate: 50, interval: 0}},            {
    type: 'value', gridIndex: 2, name: 'Income', axisLabel: {
    rotate: 50, interval: 0}},            {
    type: 'value', gridIndex: 3, name: 'Life Expectancy', axisLabel: {
    rotate: 50, interval: 0}}        ],        yAxis: [            {
    type: 'category', gridIndex: 0, name: 'Country', boundaryGap: false, axisLabel: {
    rotate: 50, interval: 0}},            {
    type: 'value', gridIndex: 1, name: 'Income'},            {
    type: 'value', gridIndex: 2, name: 'Population'},            {
    type: 'value', gridIndex: 3, name: 'Population'}        ],        dataset: {            dimensions: [                'Income',                'Life Expectancy',                'Population',                'Country',                {
    name: 'Year', type: 'ordinal'}            ],            source: data        },        series: [            {                type: 'scatter',                symbolSize: symbolSize,                xAxisIndex: 0,                yAxisIndex: 0,                encode: {                    x: 'Income',                    y: 'Country',                    tooltip: [0, 1, 2, 3, 4]                }            },            {                type: 'scatter',                symbolSize: symbolSize,                xAxisIndex: 1,                yAxisIndex: 1,                encode: {                    x: 'Country',                    y: 'Income',                    tooltip: [0, 1, 2, 3, 4]                }            },            {                type: 'scatter',                symbolSize: symbolSize,                xAxisIndex: 2,                yAxisIndex: 2,                encode: {                    x: 'Income',                    y: 'Population',                    tooltip: [0, 1, 2, 3, 4]                }            },            {                type: 'scatter',                symbolSize: symbolSize,                xAxisIndex: 3,                yAxisIndex: 3,                encode: {                    x: 'Life Expectancy',                    y: 'Population',                    tooltip: [0, 1, 2, 3, 4]                }            }        ]    };    myChart.setOption(option);});复制代码
