vue2.0加载不出echarts引用的百度地图
1.点击选择其中一个选项就会进行ajax请求echarts并更新，现在是echarts的中加载的百度地图出不来。
2.点击选项都能够正确获取到json数据
3.图表只显示了echarts中的visualMap，实际的地图并没有显示
4.listValue[0]的数据格式见第一个图
5.是不是我引入百度地图到echarts里有问题？。。。
export default{ data() {
return {
}
},
mounted (){
myChart=this.$echarts.init(document.getElementById('myMain'))
this.$bus.on('echarts-on',this.ready);//这条语句是响应选择组件选择数据更新时再更新echarys
},
methods:{
ready(options){
myChart.setOption(this.echartsFunc(options))
},
echartsFunc(listValue) {
console.log(listValue[0])
// 配置option
var options = {
bmap: {
// 百度地图中心经纬度
center: [121.549703, 29.927862],
// 百度地图缩放
zoom: 12,
// 是否开启拖拽缩放，可以只设置 'scale' 或者 'move'
roam: true,

回答：
我在vuejs2.0中没有引用扩展插件require('echarts/extension/bmap/bmap');
感谢各位大神相助！
回答：
有可能不是Vue的问题，可能是你数据结构本身的问题
首先，你的数字看起来像数字，但是其实是字符串，
"121.551583"这种是字符串而并非数字。echarts可能解析不了字符串的值由于你的
series类型时scratter，所以你的data数据结构应该按照[[X1, Y1], [X2, Y2], ...]的方法构建具体数据结构参照：http://echarts.baidu.com/opti...
