横屏的方式
1、直接控制手机屏幕显示方向，让手机屏幕方向变成横屏
onLoad(){
//解除屏幕锁定，然后锁定屏幕方向未横屏
plus.screen.unlockOrientation();
plus.screen.lockOrientation('landscape-primary');
},
onUnload() {
plus.screen.lockOrientation('portrait'); //锁死屏幕方向为竖屏
},
使用这种方法，在横屏切换成竖屏的时候会导致页面显示错乱，没有找到具体好的方法解决，所以没有使用这种方法
2、手机屏幕方向还是竖屏，将页面旋转90度变成横屏显示
我采用的就是第二种方法
uni-app使用折线图可以使用echarts和ucharts两种方式
1、使用echarts
<template>
<view class="content-container">

<view class="bar-div">
