堆积条形图中的隐藏数据

我正在尝试重新使用几个月前创建的堆积条形图，如下所示：

在此处输入图片描述

我确信我用来创建的源代码是：

\documentclass{article}

我记得我花了几个小时尝试不同的东西，特别是试图弄清楚如何确保我的情节不会一个在另一个之上，并且图例会以正确的顺序出现，这时我发现我必须创建两个不同的X轴，并确保我已在布置图例的轴上重新添加了所有四个图，即使此时尚未绘制所有四个图。

我曾尝试在另一台计算机上编译相同的代码，并且可能使用了不同版本的 LaTeX 和所有模块（我当时的计算机，现在无法再使用，使用的是 Debian 稳定版，因此软件包略显过时，现在我在 Windows 上使用 TeXworks）。我得到了不同的结果：

在此处输入图片描述

正如您所见，黄色条未显示（我猜它们隐藏在红色条下，尽管它们是稍后绘制的），甚至红色条也没有在它们应该结束的地方结束。我查看了整个代码，虽然我必须承认我从来没有完全理解它，但我完全无法弄清楚它出了什么问题。

有人可以帮忙吗？

答案1

负条是从刻度线开始绘制的，-25而不是从 开始0绘制的；如果您删除第二个axis命令，这一点会更加明显。这适用于黄色和红色条，一个覆盖另一个。我不知道为什么会发生这种情况，但似乎可以通过在产生负条的绘图中添加一行零虚拟坐标来解决：

  \addplot coordinates {(0,2) (0,1) (0,0)};

示例输出

下面我对您的原始代码进行了修改，然后是一个较短的版本，其中将常用选项拉到选项中，tikzpicture而不必为每个轴重复。

答案2

PGFPlots v1.13 引入了一项新功能，可以完全按照您的需要进行操作，而无需两次绘制所有内容......

您只需要使用此compat级别或更高级别或状态stack negative=separate来axis选择。

% used PGFPlots v1.14
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
    \pgfplotsset{
        % using this `compat' level or higher changes the value of `stack negative'
        % from `on previous' to `separate' which is exactly what you want
        compat=1.13,
    }
\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
            footnotesize,
            width=.9\textwidth,
            height=.35\textwidth,
            axis y line*=left,
            axis x line*=bottom,
            xmin=-25,
            xmax=100,
            ytick=data,
            yticklabels={A, B, C},
            xtick distance=25,
            enlarge y limits={abs=0.625},

                draw=none,

            xbar stacked,
            bar width=6mm,
            area legend,
            % just added these to show that this is the desired result
            nodes near coords,
            nodes near coords style={

                {(0,2) (43,1) (40,0)};
            \addplot [blue,fill=blue] coordinates
                {(83,2) (39,1) (47,0)};

            \legend{
                strongly disagree,
