echarClickfun(myChart) {
var _this = this;
myChart.off('click');
myChart.on('click', function (params) {
if (params.componentType == "xAxis") {//点击x轴标签xAxis
_this.getchart(params.value);
} else if(params.componentType == "yAxis") {//点击y轴标签yAxis
_this.getchart(params.value);
} else {//点击柱子柱子
}
})
},
//获取二级数据重新渲染
getchart(data) {
ajaxGet('接口地址', { "province": data }, res => {
if (res.state !== 1) {
this.$message({
message: res.value || '接口报错',
type: 'error'
});
return;
}
var echartData = res.value || [];//获取二级数据
this.mychart1(echartData);
})
}
}
注：echarClickfun里边点击事件根据自己实际情况写就可以，我这里是把三种情况都列举出来了，这里还需要一个默认图表一级数据，大家真正实际写的时候加上获取接口数据就好了。
