我正在尝试绘制一些数据，其中 X 轴以字节为单位。值呈指数增长，因此我手动缩放它们以获得更好的图表。但是，我不想显示日志，而是显示实数，并且我想显示具有可变单位（字节、Kb、Mb）的数字。我很接近，但我缺少单位。

结果是：
但是，我想在 x 轴上进行小幅修改。而不是
{1,4,16,64,256,1,4,16,64,256,1,4,16,64}
我想要 {1,4,16,64,256,1Kb,4Kb,16Kb,64Kb,256Kb,1Mb,4Mb,16Mb,64Mb}
答案1
我会设置xticklabels显式并旋转它们。我认为最好对所有都使用相同的尺寸ticklabels。

答案2
已修订，使用 OP 提供的完整 MWE。我所做的就是在我认为有意义的地方添加符号。我将这些符号添加为 x 标签的一部分。我认为在数字下方标注比在数字本身标注看起来更好。
如果您更改图表的比例，则尺寸\cyclewidth也\loffset需要修改。
注意：我改变了绘图宽度以更好地符合您的图片。
