How to implement curve data display by using vue2-highcharts in Vue?-JS Tutorial-php.cn

Below I will share with you an article on how to use vue2-highcharts to display curve data in Vue. It has a good reference value and I hope it will be helpful to everyone.
1. The effect to be achieved is as follows:
##2. The vue front-end page is as follows:
