本节主要介绍百度echarts柱状图的实现，实现步骤如下
一、饼图实现
1，新建demo.html页面，并引入echarts的js库，在这里我们引入的是网络地址
<script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>
2，饼图容器html代码，只需一行html代码
<div id="container" style="height: 500px"></div>
饼图容器高度为500px,宽度默认，并且div的id号为container，在接下来初始化饼图的时候会用到。
3，javascript实现代码
<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
var option = null;
app.title = '坐标轴刻度与标签对齐';
option = {
backgroundColor: '#2c343c',
title: {
text: 'Customized Pie',
left: 'center',
top: 20,
textStyle: {
color: '#ccc'
}
},
tooltip : {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
visualMap: {
show: false,
min: 80,
max: 600,
inRange: {
colorLightness: [0, 1]
}
},
series : [
{
name:'访问来源',
type:'pie',
radius : '55%',
center: ['50%', '50%'],
data:[
{value:335, name:'直接访问'},
{value:310, name:'邮件营销'},
{value:274, name:'联盟广告'},
{value:235, name:'视频广告'},
{value:400, name:'搜索引擎'}
].sort(function (a, b) { return a.value - b.value}),
roseType: 'angle',
label: {
normal: {
textStyle: {
color: 'rgba(255, 255, 255, 0.3)'
}
}
},
labelLine: {
normal: {
lineStyle: {
color: 'rgba(255, 255, 255, 0.3)'
},
smooth: 0.2,
length: 10,
length2: 20
}
},
itemStyle: {
normal: {
color: '#c23531',
shadowBlur: 200,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
if (option && typeof option === "object") {
myChart.setOption(option, true);
}
</script>4，用浏览器打开demo.html，效果如下
