我必须遵循乳胶代码:
\usepackage{tikz}
\usepackage{pgfopts}
\usepackage{pgfplotstable}
\begin{document}
\begin{tikzpicture}[scale=1]
\begin{axis}[minor tick num=1,
scale only axis,
height=5cm,
width=\textwidth*0.8,
xlabel=\textnumero contestants,
ylabel style={overlay},
yticklabel style={overlay},
xticklabel style={overlay},
ylabel=,
ybar,
ymin=0,
legend style={at={(0, 1)},anchor=west},
legend entries={\textnumero matches, \textnumero rounds}]
\addplot [draw opacity=0,fill=yellow!50] table [x index=0, y index=1] {charts/merge_no_matches_rounds.csv};
\addplot [draw opacity=0,fill=green] table [x index=0, y index=2] {charts/merge_no_matches_rounds.csv};
\end{axis}
\end{tikzpicture}
\end{document}
结果如下:
数据文件如下所示:
2 1 1
4 4 3
6 9 6
8 11 6
10 17 9
12 21 9
14 23 9
. . .
92 181 18
94 185 18
96 189 18
98 191 18
100 193 18
黄色区域看起来不错,但绿色区域有奇怪的偏移。我该如何解决这个问题?
答案1
您不应该在这里使用直方图。如果黄色数据的一个值低于相应的绿色值,那么您的绘图想法就不再实用了。您应该使用真实的条形图或真实的堆叠图,而不是混合使用。(实际上,简单的曲线是最好的)
不过,我还是为您提供了一个解决方案:
