line.vue:148 [ECharts] DEPRECATED: textStyle hierarchy in label has been removed since 4.0. All text

line.vue:148 [ECharts] DEPRECATED: textStyle hierarchy in label has been removed since 4.0. All textStyle properties are configured in label directly now.

textStyle 已经从 label 中直接删除了，textStyle 下的内容直接写到label 里面

错误写法

label: { 
   textStyle: {  
           fontWeight: 500,
          fontSize: 10,
   }
}

正确写法：删掉textStyle，textStyle下面的内容直接写在label下

label: { 
       fontWeight: 500,
       fontSize: 10,
}
