各位同仁、各位朋友，大家好！
我试图摆脱 x 标签中的 .10^-3，但出现了问题并且我找不到错误。
我尝试过x tick label style={/pgf/number format/.cd,fixed,fixed zerofill,precision=3},但是它抛出了错误。
这是代码和它产生的情节：

您可以通过添加轴选项来消除乘数scaled x ticks=false，但这样刻度就会很密集。因此我建议只打印每隔一个 x 刻度。

我（个人）不喜欢ticklabels你的（OP）代码中出现这样的情况，也不喜欢土拨鼠的答案。我更喜欢将缩放添加到轴标签。
当然，你可以简单地删除/清空tick scale binop并添加缩放用手到轴标签。但我希望有更多自动化解决方案这当然有点复杂......
有关详细信息，请查看代码中的注释。
