我希望有人能帮助我。我正在尝试在论文中插入一些条形图，我花了很长时间寻找解决方案。我发现另一个问题，其中的答案是以下代码：
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\begin{document}
\pgfplotstableread[row sep=\\,col sep=&]{
interval & carT & carD & carR \\
0--2 & 1.2 & 0.1 & 0.2 \\
2--5 & 12.8 & 3.8 & 4.9 \\
5--10 & 15.5 & 10.4 & 13.4 \\
10--20 & 14.0 & 17.3 & 22.2 \\
20--50 & 7.9 & 21.1 & 27.0 \\
50+ & 3.0 & 22.3 & 28.6 \\
}\mydata
\begin{tikzpicture}
\begin{axis}[
ybar,
bar width=.5cm,
width=\textwidth,
height=.5\textwidth,
legend style={at={(0.5,1)},
anchor=north,legend columns=-1},
symbolic x coords={0--2,2--5,5--10,10--20,20--50,50+},
xtick=data,
nodes near coords,
nodes near coords align={vertical},
ymin=0,ymax=35,
ylabel={\%},
]
\addplot table[x=interval,y=carT]{\mydata};
\addplot table[x=interval,y=carD]{\mydata};
\addplot table[x=interval,y=carR]{\mydata};
\legend{Trips, Distance, Energy}
\end{axis}
\end{tikzpicture}
\end{document}
我只是复制了这段代码，没有做其他任何事情。pdf 无法编译，显示的错误如下：

我对此一无所知（我使用 Texstudio），也不知道该怎么做。如果已经存在解决此问题的方法，请分享链接。如果我的英语不够清楚，我很抱歉。非常感谢任何愿意帮助我的人。
