javascript - How does php elegantly pass data to the date attribute of front-end Echarts?

For example, the two kinds of data marked in the red box in the screenshot are arrays of assoc_array type that I took directly from the database. How do I convert the array, or what kind of array or json should PHP use to pass to the front end? ? Can you give me an example? Thank you! ! ! ~

You can write a function to generate an object based on the object of each item in the data array, then traverse your array to generate the value of each item of the array you need, and add it to a new array, which is equivalent to an object array. This is how to process the data in the second red box. The first one is directly an array. Anyway, it’s the same thing
The above is just my opinion, maybe it’s not mature enough, please forgive me.
