Please help me

I drew the graph using react-chartjs-2.
But I don't know how to solve Top xAxes and tooltip customization.
Please help me.

Here is my current graph using react-chartjs-2.

Please ask questions on StackOverflow: https://stackoverflow.com/questions/tagged/chart.js

You could try adding a second scale as a category scale with four labels for the years

Please see https://www.chartjs.org/docs/latest/configuration/tooltip.html for the tooltip

thank you for your help
