我必須遵循乳膠代碼:
\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}
這是結果:
資料檔如下所示:
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
黃色區域看起來不錯,但綠色區域有一個奇怪的偏移。我該如何解決這個問題?
答案1
您不應該在這裡使用直方圖。如果黃色資料的一個值低於相應的綠色值,則您的繪圖想法不再實用。您應該使用真實的條形或真實的堆疊,而不是混合。 (實際上,簡單的曲線是最好的)
不過,我還是為你提供了一個解決方案:
