pgfplots ybar 堆叠-文本而不是数字

Question

我尝试使用 tikz 制作我的第一个图表，并且已经成功了很大一部分。

有两件事我没能完成：

• 使用文本标签而不是数字，我尝试使用注释，但弄清楚将它们放在哪里以及当发生变化时重新排列是很困难的......
• 改变图表的整体高度

我希望有人能够帮助我：）谢谢！

您可以添加point meta=explicit symbolic到axis选项中，并将坐标写为(x,y) [text]。要设置高度，请使用height=<length>。

\documentclass[border=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{width=7cm,compat=1.14} % with compat=1.9 or higher, the bar labels are placed in the center of the bar. 1.14 is the newest version at the moment
\begin{document}
\begin{tikzpicture}
\begin{axis}[
ybar stacked,
width=.9\textwidth,
height=\textwidth, % <-- added
bar width=.7\textwidth,
point meta=explicit symbolic, % <-- added
nodes near coords,
enlargelimits=0,
ylabel={Spannung in V},
symbolic x coords={tool1
%, tool2, tool3, tool4, tool5, tool6, tool7
    },
xtick=data,
 %  x tick label style={rotate=45,anchor=east},
xtick style={draw=none},
xticklabel=\empty
]

\addplot+[ybar] plot coordinates {(tool1,0) [a]};
\addplot+[ybar] plot coordinates {(tool1,20) [b]};
\addplot+[ybar] plot coordinates {(tool1,4) [c]};
\addplot+[ybar] plot coordinates {(tool1,12) [d]};
\addplot+[ybar] plot coordinates {(tool1,12) [e]};
\addplot+[ybar] plot coordinates {(tool1,4) [f]};
\addplot+[ybar] plot coordinates {(tool1,2) [g]};
\addplot+[ybar] plot coordinates {(tool1,4) [h]};
\addplot+[ybar] plot coordinates {(tool1,2) [i]};
\end{axis}
