Tikzplot 左下角出现奇怪的数字

我正在尝试使用非常小的数字创建一个图表，我认为我已经成功了。问题是左下角有一个文本覆盖层，我不知道如何删除它。如能提供帮助，我将不胜感激。谢谢！

OP 的示例引发了几个错误，其中第一个是

! Package pgfkeys Error: I do not know the key '/pgf/number format/at', to which you passed '(xticklabel cs:0.9,5pt)', and I am going to ignore it. Perhaps you misspelled it.

这是由于/pgf/number format/.cd使用

    tick label style={font=\scriptsize,
                      /pgf/number format/.cd, fixed, fixed zerofill},

这会将默认路径更改为/pgf/number format。事实证明，pgfplots除了传递给 的键之外，还使用了其他键tick label style，而这些“其他键”要求默认路径不变。

使用/pgf/number format/fixed, /pgf/number format/fixed zerofill可消除错误以及报告的“奇怪的数字覆盖”。

PS：当编译出现错误时，最好集中精力于第一个错误并在问题描述中提及它。
