![Tikz 堆积条形图-更改标签](https://linux22.com/image/343118/Tikz%20%E5%A0%86%E7%A7%AF%E6%9D%A1%E5%BD%A2%E5%9B%BE-%E6%9B%B4%E6%94%B9%E6%A0%87%E7%AD%BE.png)
我有以下条形图。
其代码如下:
\documentclass{standalone}
\usepackage[x11names]{xcolor}
\usepackage{tikz,pgfplots}
\usepackage{graphicx}
\usepackage{ifthen}
\usetikzlibrary{arrows, arrows.meta, bending, shapes, 3d, calc, fit, positioning}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
ybar stacked,
scale = 0.4,
bar width=15pt,
nodes near coords,
enlargelimits=0.15,
legend style={at={(0.5,-0.20)},
anchor=north},
ylabel={\#bla},
grid,
symbolic x coords={a,b,c,d},
xtick=data,
x tick label style={anchor=north},
]
\addplot+[ybar] plot coordinates {(a,5) (b,15) (c,1) (d,10)};
\addplot+[ybar] plot coordinates {(a,8) (b,29) (c,0) (d,1)};
\legend{\strut blubb, \strut peng}
\end{axis}
\end{tikzpicture}
\end{document}
显然,这个情节有几个地方不太好看。我想改变的是:
- 使条形图上的数字(蓝色和红色数字)变小,但不使轴标签(黑色数字)也变小。
- 控制条形图(蓝色和红色)上数字的位置。特别是,我不希望它们重叠并延伸到条形图边框之外,例如左侧的 5。
- 红色数字似乎总是将代码中给出的两个值相加。我不想这样。我希望蓝色数字代表我有多少个“blubb”,红色数字代表我有多少个“peng”。
有人能帮我吗?谢谢!

答案1
我很确定以下解决方案解决了第 1 点和第 3 点,但我不知道我是否正确理解了第 2 点。
第 1 点可以通过添加
nodes near coords style={
font=\tiny,
},
自 PGFPlots v1.9 起,Point 3 为默认值。
对于第 2 点,我调整了给出的解决方案这里,现在节点被放置在条形图的“上方”,如果当前条形图值小于新样式的给定值,即在这种情况下
nodes near coords custom=5,
这对于给定的值很有效,因为较小的值始终是最后给出的(或者接下来的是零,特殊处理程序会跳过这些条目)。

我找到了这个粗略的解决方案,但它不能满足您的所有观点:
\documentclass{standalone}
\usepackage[x11names]{xcolor}
\usepackage{tikz,pgfplots}
\usepackage{graphicx}
\usepackage{ifthen}
\usetikzlibrary{arrows, arrows.meta, bending, shapes, 3d, calc, fit, positioning}
\pgfplotsset{width=7cm,compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
ybar stacked,
grid,
bar width=15pt,
nodes near coords,
enlargelimits=0.2,
legend style={at={(0.5,-0.20)},
anchor=north,legend columns=-1},
ylabel={\#bla},
symbolic x coords={a,b,c,d},
xtick=data,
x tick label style={anchor=north},
]
\addplot+[ybar] plot coordinates {(a,2) (b,15) (c,1) (d,10) };
\addplot+[ybar] plot coordinates {(a,8) (b,29) (c,0) (d,1)};
\legend{blubb, peng}
\end{axis}
\end{tikzpicture}
\end{document}
