pgfplots：重复 y 轴标签

Question

我想绘制一个线图。坐标 y 的值从 0 到 0.035。

但是，y 标签刻度完全错误，有重复值，例如有两个“0.03”标签。因此，绘图当然也是错误的。

\documentclass[a4paper]{article}
\usepackage{pgfplots}
\pgfplotsset{width=0.9\textwidth,compat=newest}

\begin{tikzpicture}
\begin{axis}
[
axis lines = left,
xlabel = Instance,
ylabel = {Average Deviation (\%)},
scaled y ticks=false, 
y tick label style={/pgf/number format/fixed, /pgf/number format/precision=2},
symbolic x coords={1,2,3,4,5,6,7,8,9,10,11},
xtick=data,
xticklabels={$10\times5EG$,$10\times5EH$,$10\times5FH$,$12\times3EG$,$12\times3EH$,$12\times3FG$,$12\times3FH$,$12\times4EG$,$12\times4EH$,$12\times4FG$,$12\times5EG$},
]
\addplot
[
color=red,
mark=square
]
coordinates{(1,0.019)(2,0.029)(3,0.000)(4,0.015)(5,0.003)(6,0.000)(7,0.000)(8,0.035)(9,0.000)(10,0.012)(11,0.004)};
\legend{MBBOTS algorithm}
\end{axis}
\end{tikzpicture} 

\end{document}

感谢帮助。

Answer 1

这里有几点。

1. 你不需要

    symbolic x coords={1,2,3,4,5,6,7,8,9,10,11},
    xtick=data
   

2. 提高精度/pgf/number format/precision=5。现在由于您使用低精度0.015，因此0.02显示相同。

3. 您有较长的 xtick 标签。因此，旋转它们将是一个好主意。

有了这些，我们就有：

\documentclass[a4paper]{article}
\usepackage{pgfplots}
\pgfplotsset{width=0.9\textwidth,compat=newest}

\begin{document}
\begin{tikzpicture}
\begin{axis}
[
axis lines = left,
xlabel = Instance,
ylabel = {Average Deviation (\%)},
scaled y ticks=false,
y tick label style={/pgf/number format/fixed, /pgf/number format/precision=5},
%symbolic x coords={1,2,3,4,5,6,7,8,9,10,11},
%xtick=data,
x tick label style= {rotate=45,anchor=north east},
xticklabels={$10\times5EG$,$10\times5EH$,$10\times5FH$,$12\times3EG$,$12\times3EH$,$12\times3FG$,$12\times3FH$,$12\times4EG$,$12\times4EH$,$12\times4FG$,$12\times5EG$},
]
\addplot
[
color=red,
mark=square
]
coordinates{(1,0.019)(2,0.029)(3,0.000)(4,0.015)(5,0.003)(6,0.000)(7,0.000)(8,0.035)(9,0.000)(10,0.012)(11,0.004)};
\legend{MBBOTS algorithm}
\end{axis}
\end{tikzpicture}

\end{document}
