效果:

//index.js
var wxCharts = require('../../utils/wxcharts-min.js');
const app = getApp();
var ringChart = null;

      delta: 1,
    })
  },
  onLoad: function (e) {
    //  高度自适应
    var windowWidth = '', windowHeight = '';    //定义宽高
    try {
      var res = wx.getSystemInfoSync();    //试图获取屏幕宽高数据
      windowWidth = res.windowWidth / 750 * 690;   //以设计图750为主进行比例算换
      windowHeight = res.windowWidth / 750 * 550    //以设计图750为主进行比例算换
    } catch (e) {
      console.error('getSystemInfoSync failed!');   //如果获取失败
    }
