如何为Highcharts的Y轴标签gutter增加空间避免标签截断

针对你遇到的Y轴标签被竖线截断、需要给标签区域增加40px空间的问题，可通过以下调整解决：

关键修改点 #

• 移除yAxis.offset: -1：该负偏移会将Y轴向图表内部挤压，导致标签与轴重叠
• 给Y轴标签添加x: 40：让标签向远离Y轴的方向偏移40px，避免被竖线截断
• 增加chart.spacingRight: 60：给图表右侧预留足够空间，确保标签和后续注释不会超出容器

说明 #

• yAxis.labels.x控制标签相对于Y轴的水平位置，设置为40正好满足你需要的40px间距要求
• chart.spacingRight的值可根据你后续添加注释的大小调整，确保所有内容都能完整显示
• 移除负偏移后，Y轴回到默认的右侧位置，不会再挤压标签空间
