tikzpicture 条形图中的引用

Question

我正在尝试绘制一个条形图，pgfplots我想在其中添加对 x 坐标的引用。输出中出现以下错误。

Paragraph ended before \XC@definec@lor was complete和Argument of \XC@definec@lor has an extra }. \end{axis}

但是，当我删除引文时，一切似乎都正常。这是 MWE。

\begin{tikzpicture}
            \begin{axis}[
                ybar,
                enlargelimits=0.15,
                legend style={at={(0.5,-0.2)},
                    anchor=north,legend columns=-1},
                ylabel={Normalized Cost},
                symbolic x coords={A,\cite{somework},\cite{otherwork}},
                width={\textwidth}, 
                xtick=data,
                nodes near coords, 
                nodes near coords align={vertical},
                ]
                \addplot coordinates {(A,1) (\cite{somework},2) (\cite{otherwork},3)};
            \end{axis}
\end{tikzpicture}

\usepackage{tikz,pgfplots}我在序言中已经使用过。

Answer 1

不要使用symbolic x coords，而要使用 xtick和xticklabels。

tikz（顺便说一下，您不需要明确加载，pgfplots它会为您完成。）
