为了实现想要的效果,做了很多细节上的调整.
option代码如下:

var option = {
        tooltip: {
            backgroundColor:"#f2f6fa",
            trigger: 'axis',
            formatter: function(params){
                var param0 = params[0];
                var param1 = params[1];
                return "日期: "+param0.name+"
"+param0.seriesName+" : "+param0.value+"%
"+param1.seriesName+" : "+param1.value+"%";
            },
