echarts柱子粗细

要改变Echarts柱状图的柱子粗细，可以通过设置`barWidth`属性来实现。在`series`中，找到对应柱状图的配置项，设置`barWidth`的值即可改变柱子的粗细。例如，在给定的示例中，将`barWidth`设置为17即可改变柱子的粗细。

series: [
  {
    data: [120, 200, 150, 80, 70, 110, 130],
    type: 'bar',
    showBackground: true,
    barWidth: 17,
    backgroundStyle: {
      color: 'rgba(180, 180, 180, 0.2)'
    }
  }
]

通过修改`barWidth`的值，可以根据需求调整柱子的粗细。<span class="em">1</span><span class="em">2</span>
