var myChart = echarts.init(document.getElementById('main'));
function randomData() {
return Math.round(Math.random()*1000);}
option = {

calculable: true
},
toolbox: {
show: true,
orient: 'vertical',
left: 'right',
top: 'center',
feature: {
dataView: {readOnly: false},
restore: {},
saveAsImage: {}
}
},
series: [
{
name: '省份数据',
type: 'map',
mapType: 'china',
roam: false,
