dingshengqin opened a new issue #15366:
URL: https://github.com/apache/echarts/issues/15366
需求：我想实现当input的时间数据发生变化时，粗发echarts表格的更新
问题：时间数据变化时console.log没问题，ajax请求没有问题，数据return也没有问题，echarts显示没有数据
报错：echarts-all.js:9 Uncaught TypeError: Cannot read property 'getAxis' of
undefined
麻烦大神指导！感谢！
document.getElementById("end-time").onchange = function(){
var myCharts3 =
echarts.init(document.getElementById('main'));
var start_time1 =
document.getElementById("start-time").value;
var end_time1 = document.getElementById("end-time").value;
{#document.write(start-time1)#}
{#document.write(end_time1)#}
