点击button切换数据源echarts 配置项内容和展示

通过点击底部的两个按钮，获取索引值，然后传进来给图表，这里我暂时用定时器模拟点击事件

      var indexs= 0
//indexs 是在点击的时候，传进来的一个值，对应下面的数组里面的内容，


setInterval(function (){
    indexs++;
    if(indexs ==2){
        indexs=0;
    }
    console.log(indexs)
    priceAnalysis(indexs)
},5000)



 priceAnalysis(indexs)

var indexs= 0
 function priceAnalysis(indexs){
	var  sisData=[
	[
        {
            name:'销售量',
            type:'bar',
