2.2版本更换主题，我没能成功使用myChart.setTheme()这个方法，我找了很多，只有下面这一种方法可以
把这个目录下的主题文件拷贝到build\dist\theme下，没有theme文件夹，新建一个就行
然后在代码里这样写
<script type="text/javascript">
// 路径配置
require.config({
paths: {
echarts: './echarts-2.2.7/build/dist'
}
});
require(
[
'echarts',
'echarts/theme/dark',//加载主题
'echarts/chart/line', // 按需加载所需图表，如需动态类型切换功能，别忘了同时加载相应图表
'echarts/chart/bar', // 按需加载所需图表，如需动态类型切换功能，别忘了同时加载相应图表
'echarts/chart/pie'
],
function (ec,theme) {//把主题给传进来
var myChart = ec.init(document.getElementById('main'),theme);//设置主题
var option = {
title : {
text: '南丁格尔玫瑰图',
subtext: '纯属虚构',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
x : 'center',
y : 'bottom',
data:['rose1','rose2','rose3','rose4','rose5','rose6','rose7','rose8']
},
toolbox: {
show : true,
feature : {
mark : {show: true},
dataView : {show: true, readOnly: false},
magicType : {
show: true,
type: ['pie', 'funnel']
},
restore : {show: true},
saveAsImage : {show: true}
}
},
calculable : true,
series : [
{
name:'半径模式',
type:'pie',
radius : [20, 110],
center : ['25%', 200],
roseType : 'radius',
width: '40%', // for funnel
max: 40, // for funnel
itemStyle : {
normal : {
label : {
show : false
},
labelLine : {
show : false
}
},
emphasis : {
label : {
show : true
},
labelLine : {
show : true
}
}
},
data:[
{value:10, name:'rose1'},
{value:5, name:'rose2'},
{value:15, name:'rose3'},
{value:25, name:'rose4'},
{value:20, name:'rose5'},
{value:35, name:'rose6'},
{value:30, name:'rose7'},
{value:40, name:'rose8'}
]
},
{
name:'面积模式',
type:'pie',
radius : [30, 110],
center : ['75%', 200],
roseType : 'area',
x: '50%', // for funnel
max: 40, // for funnel
sort : 'ascending', // for funnel
data:[
{value:10, name:'rose1'},
{value:5, name:'rose2'},
{value:15, name:'rose3'},
{value:25, name:'rose4'},
{value:20, name:'rose5'},
{value:35, name:'rose6'},
{value:30, name:'rose7'},
{value:40, name:'rose8'}
]
}
]
};
console.log(theme);
//myChart.setTheme('sakura');
myChart.setOption(option);
}
);
</script>这种是模块化单文件来引入Echarts2.2的，我不会使用setTitle这个函数，也就无法实现官网的切换主题功能了，而且如果使用标签化单文件引入Echarts2.2的话，设置主题我也不会了，应该是要改JS主题文件，因为我看到里面有些都没设变量
Echart4的话就轻松多了
首先准备一些JS文件，jquery.min.js用来获取，theme主题文件我从官网下了几个
然后在代码里引用
