Steps to reproduce

tooltip: {
          trigger: "axis",
          formatter(params) {
            let cumulative = "0";
            if (params[0].value[1] >= 1000000000) {
              cumulative = (params[0].value[1] / 1000000000).toFixed(2)   "B";
            } else if (params[0].value[1] >= 1000000) {
              cumulative = (params[0].value[1] / 1000000).toFixed(2)   "M";
            } else if (params[0].value[1] >= 1000) {
              cumulative = (params[0].value[1] / 1000).toFixed(2)   "K";
            } else {
              cumulative = parseFloat(params[0].value[1]).toFixed(2)   "";
            }
            let text = `委托价<br />${params[0].value[0]}<br />累计<br />${cumulative}`;
            return text;
          },

What is expected?

应该在setoption后，tooltip应能实时更新对应位置的数据

What is actually happening?

无法更新，只显示在第一次选中的数据

Hi! We've received your issue and please be patient to get responded. 🎉
The average response time is expected to be within one day for weekdays.

In the meanwhile, please make sure that it contains a minimum reproducible demo and necessary images to illustrate. Otherwise, our committers will ask you to do so.

A minimum reproducible demo should contain as little data and components as possible but can still illustrate your problem. This is the best way for us to reproduce it and solve the problem faster.

You may also check out the API and chart option to get the answer.

If you don't get helped for a long time (over a week) or have an urgent question to ask, you may also send an email to dev@echarts.apache.org. Please attach the issue link if it's a technical question.

If you are interested in the project, you may also subscribe our mailing list.

Have a nice day! 🍵

@afanso It seems you are not using English, I've helped translate the content automatically. To make your issue understood by more people, we'd like to suggest using English next time. 🤗

TITLE

Line chart After multiple setoptions, the tooltip at the hover position of the mouse cannot update the data in real time

Version

5.1.1

Steps to reproduce

tooltip: {
trigger: "axis",
formatter(params) {
let cumulative = "0";
if (params[0].value[1] >= 1000000000) {
cumulative = (params[0].value[1] / 1000000000).toFixed(2) "B";
} else if (params[0].value[1] >= 1000000) {
cumulative = (params[0].value[1] / 1000000).toFixed(2) "M";
} else if (params[0].value[1] >= 1000) {
cumulative = (params[0].value[1] / 1000).toFixed(2) "K";
} else {
cumulative = parseFloat(params[0].value[1]).toFixed(2) "";
}
let text = Order price<br />${params[0].value[0]}<br />Accumulation<br />${cumulative};
return text;
},

What is expected?

Should be after setoption, tooltip should be able to update the data of the corresponding position in real time

What is actually happening?

Unable to update, only the data selected the first time will be displayed

this.$refs.echart.setOption(this.options, true, true); 如此调用的话，tooltip会消失，而我这里SET频率很高，1秒不到就消失

@afanso Hello, 可以帮忙看看这个PR里的动图是你想要的效果吗~
#15194

[afanso]

@ssthouse 效果非常接近，有没有代码让我学习一下

[ssthouse]

@afanso 对echart的修改在这里： https://github.com/apache/echarts/pull/15194/files

使用的话要等代码merge进echart主分支发版哦

[afanso]

@ssthouse 我看你的ECHARTS的X轴是以GATE为分类的，我这里是需要用VALUE的，效果能达到吗？

[ssthouse]

@afanso 应该是可以的。导致tooltip没有更新的原因是tooltip在判断是否要更新的时候只比较了展示数据的size，没有比较具体的value；
坐标轴的category应该没有影响；
