将bar的lable中postion固定住，让我的价格在背景bar右边显示echarts 柱状配置项内容和展示

两个tar不同组之间我用了barGap=-100%重叠在一起, 底下那个bar用来当背景色的，我想让第一个的bar的lable固定在最右方显示，官方文档中没有这种属性，都是相对的.fiexd布局怎么实现？？？？

       option = {
     backgroundColor:'black',

         text: '各医院住院收入',

         /*trigger: 'axis',*/
         axisPointer: {
             type: 'shadow'
         },
         /* formatter:'{b}<br>{c}元',*/
     },
     grid: {
         containLabel: true,
         top: 70,
