如何获得带有单个值并在侧面显示总和的堆叠条形图

如何获得带有单个值并在侧面显示总和的堆叠条形图

基于问题 我可以在条形图上放置部分值和总值。但是我的条形图有一些非常小的值,无法将数字放在某些范围内。我想将这些标签移到一边。我该怎么做?

请注意,在一种情况下,我有两个连续的小范围,因此将这些值放在交替的两侧会很棒。

提前致谢!

以下是我目前所掌握的信息:

在此处输入图片描述

以及相关代码:

\documentclass[tikz,border=10pt]{standalone}

因此,从文档中可以看出,这个问题有点难以解决,nodes near coords alignvisualization depends on应该有灵丹妙药。奇怪的是,它失败了。

相反,必须将其visualization depends onevery node near coord/.append style解决方法结合起来。

还必须包含其内联数据,如下所述@Symbol1,以防止错误。

Package PGF Math Error: Unknown function `thisrow_unavailable_load_table_directly' (in 'thisrow_unavailable_load_table_directly')

我还必须将数据重新组织成表格形式。我以为可以使用元标记和原始坐标数据,但我还没有尝试过。

\documentclass[tikz,border=10pt]{standalone}
\usepackage{pgfplots,pgfplotstable}
\pgfplotsset{compat=1.12}

\begin{document}
  \begin{tikzpicture}
    \pgfplotsset{
        show sum on top/.style={
            /pgfplots/scatter/@post marker code/.append code={%
                \node[
                at={(normalized axis cs:%
                    \pgfkeysvalueof{/data point/x},%
                    \pgfkeysvalueof{/data point/y})%
                },
                anchor=south,
                ]
                {\pgfmathprintnumber{\pgfkeysvalueof{/data point/y}}};
            },
        },
    }

    \begin{axis}[ybar stacked,
        nodes near coords,
        title={Energy spent},
        xtick={0,...,4},
        bar width=25pt,
        ymin=0,
        enlarge x limits=0.125,
        ylabel = Energy (J),
        legend entries={A,
            B,
            C,
            D},
        legend pos=outer north east,
    ]

    \addplot+[visualization depends on={value \thisrow{Ax} \as \xdelta},
              visualization depends on={value \thisrow{Ay} \as \ydelta},
              every node near coord/.append style={xshift=\xdelta,yshift=\ydelta}] table [x={x}, y={A}] {
      x A      Ax Ay 
      0 0      0  0

     table [x={x}, y={B}] {

      3 9.681 0  0

    \addplot+[visualization depends on={value \thisrow{Cx} \as \xdelta},

     table [x={x}, y={C}] {

      2 0.247  -25 -10  
      3 1.975  -25 -10  
    };
    \addplot+[visualization depends on={value \thisrow{Dx} \as \xdelta},
              visualization depends on={value \thisrow{Dy} \as \ydelta},
              every node near coord/.append style={xshift=\xdelta,yshift=\ydelta},
              show sum on top] 
     table [x={x}, y={D}] {
      x D      Dx  Dy
      0 3.772  0   0 
      1 1.075 -25  0 
      2 0.439 -25  0
      3 2.066 -25  0
    };

    \end{axis}
  \end{tikzpicture}
 \end{document}

注意 pgfplots 有足够合理的默认值,因此我插入了和选项+之间,因此\addplot[]导致颜色略有不同。
