用于频率分析的 PGF 图

我想创建一个小型的 PGF 图来表示德语的字母频率。我尝试了很多次，但还是没能得到结果。以下是我目前所做的：

\documentclass[a4paper, 11pt]{book} % A4 paper size and default 11pt font size
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}

\begin{tikzpicture}
\scriptsize
\begin{axis}[
ybar,
width = \textwidth,
ylabel={Prozentsatz},
symbolic x coords={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z},
xtick=data,
nodes near coords,
nodes near coords align={vertical},
]
\foreach \x in {

}{
\addplot coordinates {\x};
}
\end{axis}
\end{tikzpicture}

\end{document}

我的主要问题是，并非所有绘制的坐标都在绘图区域中。我尝试过，width = \textwidth但这只会产生更多问题。此外，x 轴上只有一个字母，而不是整个字母表，并且条形图之间有很大空间，我无法将其最小化。有人能帮我吗？

像这样：

在此处输入图片描述

你对foreach循环的使用是错误的。更好/正确的方法是将循环内容移动到坐标

\documentclass[a4paper, 11pt]{book} % A4 paper size and default 11pt font size
\usepackage{pgfplots}
\begin{document}

\begin{tikzpicture}
\scriptsize
\begin{axis}[width=\linewidth,
        ybar = 1mm,
   bar width = 3mm,
enlarge x limits=0.04,
ylabel={Prozentsatz},
symbolic x coords={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z},
xtick=data,
ymin=0,
nodes near coords,
nodes near coords style={rotate=90, anchor=west, font=\footnotesize},
]
\addplot coordinates {
(a,6.51)
(b,1.89) 
(c,3.06)  
(d,5.08) 
(e,17.40) 
(f,1.66) 
(g,3.01) 
(h,4.76)  
(i,7.55) 
(j,0.27)
(k,1.21)
(l,3.44)
(m,2.53)
(n,9.78)
(o,2.51)
(p,0.79)
(q,0.02)
(r,7.00)
(s,7.27)
(t,6.15)
(u,4.35)
(v,0.67)
(w,1.89)
(x,0.03)
(y,0.04)
(z,1.13)
};

\end{axis}
\end{tikfzpicture}

如果您想比较不同语言的字母频率，那么您应该形成一个表格而不是坐标。
