我在表格中有一些元數據,我將它們作為條形標籤包含在我的圖中。我想指定這些標籤是計時的,例如 15.8 秒。我不知道如何將“秒”文字附加到標籤上。
這是一個 MWE:
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
\begin{document}
\pgfplotstableread{
c1 c2 c3 c4 c5 c6 c7 c8 c9 c10 c11
1 94 0 5 6 6 15.8 2.0 37.5 42.3 42.3
2 93 0 5 7 7 16.1 2.1 30.7 43.1 42.5
3 97 0 11 13 13 18.6 1.9 39.0 51.6 51.9
4 87 34 93 93 93 34.6 34.6 93.8 93.3 92.4
}\inittable
\begin{tikzpicture}
\begin{axis}[
ybar, bar width=10pt,
width=6in, height=2.5in,
ymin=-5, ymax=120, ytick={0,50,100},
xmin=0, xmax=5, xtick={1,2,3,4},
point meta=explicit,
nodes near coords, every node near coord/.append style={
anchor= west, rotate=90, font=\footnotesize},
tick label style={font=\footnotesize},
]
\addplot table[x=c1,y=c2,meta=c7] {\inittable};
\addplot table[x=c1,y=c3,meta=c8] {\inittable};
\addplot table[x=c1,y=c4,meta=c9] {\inittable};
\addplot table[x=c1,y=c5,meta=c10] {\inittable};
\addplot table[x=c1,y=c6,meta=c11] {\inittable};
\end{axis}
\end{tikzpicture}
\end{document}
答案1
的預設值node near coords
是\pgfmathprintnumber\pgfplotspointmeta
:它只是將點元值列印為數字。但它會在 Ti 內完成kZ 節點,因此您只需向其添加文字即可,它也會進入該節點。所以,你想做的事情都可以透過 來實現nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}~secs}
。但是,如果您這樣做,您會看到一些“秒”延伸到上軸邊框之上,因此您還需要添加類似enlarge y limits={upper, abs value=20}
.這兩項更改將為您提供以下輸出:
然而,就我個人而言,我寧願使用第二個符號,如下所示siunitx
:s
nodes near coords={%
${\pgfmathprintnumber\pgfplotspointmeta} \, \si{\second}$%
}
請注意xtick distance=1
和ytick distance=50
,它稍微簡化了您的程式碼。另外,我用來\pgfplotsset{compat=1.16}
確保即使在未來版本的pfgplots
.
