How to use Vue-Chartjs to dynamically update line charts efficiently?

I have this working code that updates a chart where onMount simulates some kind of update. But completely destructuring the array and rebuilding it with new values in the OnMounted hook doesn't seem very efficient? I have tried using reactive components for data_values and label_values but that results in a maximum call stack exceeded error when the update fires.

Multiline chart in React

I'm basically trying to make a simple chart using Recharts in React. The problem I'm having is that I can't make multiple rows because the X-axis is different for both datasets.

Can the LightningChart shared axis feature stack 2 line series on multiple Y axes with a shared X axis?

I need to create stacked line chart. Basically I want to create 2 Y axes and have them share a common X axis. The two Y-axes should be stacked on top of each other.

Is there any way to convert it

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records. I want to first perform a query limited to 3 records, and then sort the results of this query by a column called ContactName. I think this might be a nested query. Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit
