Echarts3之html2canvas下载图表（后续生成PDF）
然后引入Echarts。对应自己的echarts.js路径
index.jsp页面
<%@ page language=“java” pageEncoding=“UTF-8”%>
<%–引入JSTL核心标签库 --%>
<%@ taglib prefix=“c” uri=“http://java.sun.com/jsp/jstl/core”%>
<%
String base = request.getScheme()+“😕/”+request.getServerName()+“:”+request.getServerPort()+“”+request.getContextPath();
%>
然后是province.js代码：
function pie(legend_data,data) {
var option = {
tooltip: {
formatter: function(params, ticket, callback) {
return params.name + " : " + params.value + " (" + params.percent + “%)”;
}
},
legend: {
orient: ‘vertical’,
right: ‘right’,
data : legend_data
},
series: [{
name: ‘病例数量’,
type: ‘pie’,
radius: ‘50%’,
center: [‘40%’, ‘60%’],
data: data,
itemStyle: {
normal: {
label: {
formatter: function(params, ticket, callback) {
return params.name + “: ” + params.value + " (" + params.percent + “%)”;
}
},
}
