区别于纵向表格
xAxis和yAxis对调
要将label全部固定到最右侧： 隐藏一个柱形 为每个label设置固定的偏移距离 offset: [300 - 80, 0]
在data中加入label的配置 根据现在的值生成距离右侧的偏移
更新方法
chart.setOption({series: [{},{data: data.map(v => ({value: offset,label: {show: true,position: "right",color: "#00D753",fontWeight: "bold",fontSize: fontSize,formatter: `${v}`,fontFamily: "MyCustomFont",fontStyle: "italic",distance: 0,offset: [300 - 80, 0],},})),},{data,},],})
data: data.map(v => ({value: offset,label: {show: true,position: "right",color: "#00D753",fontWeight: "bold",fontSize: fontSize,formatter: `${v}`,fontFamily: "MyCustomFont",fontStyle: "italic",distance: 0,offset: [300 - 80, 0],},})),
