Hello, I encountered such a problem when using Echarts. After reading the document and spending some time, I still haven't solved it. I hope you can provide some ideas.
Attached is the screenshot. Here is the problem description： This table shows the daily wind direction in a month, for example, 0 is no wind, 45 is east wind, 315 is northwest wind, etc Now you want to display the wind direction directly. For example, if it is 45, you want to display ne. If it is 315, you want to display NW instead of numbers So where should I modify to achieve this effect? Check the documentation. I added the formatter method in tooltip. The project has no effect. The source code written by Vue
