var cities = ['北京', '上海', '深圳', '广州', '苏州', '杭州', '南京', '福州', '青岛', '济南', '长春', '大连', '温州', '郑州', '武汉', '成都', '东莞', '沈阳', '烟台'];
var barHeight = 50; option = {
title: {
text: '在中国租个房子有多贵?',
subtext: '市中心一室月租费(数据来源:https://www.numbeo.com)'
},

show: true,
data: ['价格范围', '均值']
},
grid: {
top: 100
},
angleAxis: {
type: 'category',
data: cities
},
tooltip: {
show: true,
formatter: function (params) {
var id = params.dataIndex;
return cities[id] + '<br>最低:' + data[id][0] + '<br>最高:' + data[id][1] + '<br>平均:' + data[id][2];

legend: {

data: ['A', 'B', 'C']
}
}; // 使用刚指定的配置项和数据显示图表。
myChart.setOption(option); </script>
</body>
</html>

步骤一:引入echarts相关JS库

<script src="echarts.js"></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/extension/dataTool.min.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.simple.min.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.js" type="text/javascript" charset="utf-8" async defer></script>
<script src="https://cdn.bootcss.com/echarts/4.1.0.rc2/echarts.common.min.js" type="text/javascript" charset="utf-8" async defer></script>

步骤二:

下边JS中加入这句话:var myChart = echarts.init(document.getElementById('main'));

下边JS中末尾加入这句话:

// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option);

中间就是demo中的JS示例代码了;
