將 Groupplots 與不連續軸結合來修改比例

Question

我想創建一個不連續的圖，可以在不連續縮放的情況下從 10%「跳躍」到例如 50%。我想我自己得到了大部分解決方案並將其發佈在下面。 「問題」是我無法將第一個繪圖組定義為 ，ymin=0,ymax=6,將第二組定義為ymin=45,ymax=80,。當我定義第一個範圍時，它將繪圖的這一部分移至最右側，並將其一部分移出繪圖（我不明白為什麼）。看這張圖： 當我定義第二個範圍時，繪圖只是“消失”，文件的這一部分僅保留空白。

目前這看起來像： 除了我想在圖的“底部”右側部分上顯示的幾乎是什麼之外，只有 4 個具有“相同”高度的條形，因為它們在上部和左下部分上不同，實際上可以看到酒吧的不同高度，不像現在的樣子。當然，在上部，不應顯示左側條形，因為它們的值較小。

我希望你能幫我解決這個問題

我認為，您的方法更適合折線圖，但不適用於長條圖。

您可以使用具有不同比例的兩個軸：

\documentclass{article}

\usepackage{graphicx}      
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}

\usepackage{xcolor} 
\definecolor{ForestGreen}{RGB}{34,139,34} 
\definecolor{Gold}{RGB}{218,165,32} 
\definecolor{MediumBlue}{RGB}{25,25,205} 
\usepackage{capt-of} 
\begin{document} 

\begin{tikzpicture} 
\pgfplotsset{
      width=95mm,
      axis x line=box,
      axis y discontinuity=crunch,
      ybar, 
      xmin=0,xmax=1,
      xtick={0,1},
      xticklabels={\# Variables (\%),Pipeline Utilization (\%)}, 
      enlarge x limits=.5,
}

\begin{axis}[%
      ymin=45, ymax=80,
      height=45mm,
      bar width=.68cm,
      ytick={60,80},
      nodes near coords,
      nodes near coords align={vertical}, 
      every node near coord/.append style={font=\small}]

      \addplot [color=purple, fill = purple,] coordinates {(1,62.05)}; 
      \addplot [color=orange, fill = orange,] coordinates {(1,63.53)}; 
      \addplot [color=ForestGreen, fill = ForestGreen,] coordinates {(1,65.51)};

\end{axis}

\begin{axis}[%

      xticklabels={,},
      nodes near coords,
      nodes near coords align={vertical},

編輯：目前無法使用pgfplots選項來轉移不連續性問題。此外，當裝飾應用於軸時似乎存在問題，特別是在使用pre length和時post length，如文檔所述這裡。儘管如此，我還是設法使用替代軸的路徑替換裝飾來繪製自訂的不連續性緊縮。遺憾的是，您似乎無法使用axis x line=box此解決方案。
