@heartAndRain What events do you need? What is the trigger mode?

100pah commented 5 years ago

There is a event "updateAxisPointer".

chart.on('updateAxisPointer', function (e) { ... });

Thanks, this solved my problem. But why can't I find a description about it in the official documentation?

更新文档还是积极点好虽然麻烦，但是值得。。。。 ”updateAxisPointer“这个事件要是不看实例，还真不知道有这个

apache / echarts
