Echarts根据窗口缩放比适配

随着窗口大小变化而变化：

window.addEventListener('resize',function(){
    myChart.resize()
})

监听窗口变化，按比例自适应图表大小

const echarts = require('echarts/lib/echarts');
require('echarts/lib/component/grid');
require('echarts/lib/chart/bar');

var chartDom = document.getElementById('main');
var myChart = echarts.init(chartDom);
var option;

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [120, 200, 150, 80, 70, 110, 130],
      type: 'bar'
    }
  ]
};

myChart.setOption(option);
window.addEventListener('resize',function(){
    myChart.resize()
})
