如何更改 tikzpicture 中的轴数字格式？

Question

我有一张 tikzpicture

但轴号和 y 标签重叠。我可以将 10^-2 更改为 0.0x 格式吗？这是代码。

\begin{tikzpicture}

\definecolor{color0}{rgb}{0,0.75,0.75}
\definecolor{color1}{rgb}{0.75,0,0.75}

\begin{axis}[
legend cell align={left},
legend style={draw=white!80.0!black},
tick align=outside,
tick pos=left,
x grid style={white!69.01960784313725!black},
xlabel={iter},
xmin=-0.45, xmax=9.45,
xtick style={color=black},
y grid style={white!69.01960784313725!black},
ylabel={validation loss},
ymin=0.02, ymax=0.15,
ytick style={color=black}

最新版本的 pgfplots 不会出现此问题。假设您需要使用较旧的兼容模式，或者无论如何都想更改数字格式，您可以添加

yticklabel style={/pgf/number format/fixed}

到你的轴的选项。
