坐标附近的节点重叠...如何向上移动

Question

我正在使用坐标附近的节点，但如您所见，底部的值重叠了。我尝试过手动放置它们，但也没有用...如何将节点向上移动，使它们不相互重叠或与线重叠！？

谢谢你！！！！！

\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{decorations.markings}
\begin{document}



\begin{tikzpicture}

    \begin{axis}[
compat=newest, 
height=0.4\textheight,
enlarge y limits={upper, value=0.3},
ymin=0,
xtick=data,
xtick={\empty},
ytick=data,
enlarge x limits = 0.5,
bar width=24pt,
title={},
symbolic x coords={0,5},
y axis line style={opacity=0},
yticklabels={\empty},
ytick style={draw=none},
axis on top,
major grid style=white,
nodes near coords
        ]

\addplot [red, line width=2pt]coordinates {(0,.1) (5,.83)};
\addplot [blue, line width=2pt]coordinates {(0,.12) (5,2.4)};
\end{axis}
\end{tikzpicture}
\end{document}

Answer 1

这是一个可能的解决方案。首先，every node near coords通过

every node near coord/.append style={yshift=-0.5cm}   % yshift can be adjusted

nodes near coords然后通过以下方式将特定的（蓝色的）添加到 addplot[options]raisebox

nodes near coords=\raisebox{0.7cm}{\pgfmathprintnumber\pgfplotspointmeta}  % 0.7 can be adjusted also.

结果如下所示

代码

\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{decorations.markings}
\begin{document}

\begin{tikzpicture}

\begin{axis}[
compat=newest, 
height=0.4\textheight,
enlarge y limits={upper, value=0.3},
ymin=0,
xtick=data,
xtick={\empty},
ytick=data,
enlarge x limits = 0.5,
bar width=24pt,
title={},
symbolic x coords={0,5},
y axis line style={opacity=0},
yticklabels={\empty},
ytick style={draw=none},
axis on top,
major grid style=white,
nodes near coords,
every node near coord/.append style={yshift=-0.5cm},
        ]
\addplot [red, line width=2pt] coordinates {(0,.1) (5,.83)};
\addplot [blue, line width=2pt,
nodes near coords=\raisebox{0.7cm}{\pgfmathprintnumber\pgfplotspointmeta}
]
coordinates {(0,.12) (5,2.4)};
\end{axis}
\end{tikzpicture}
\end{document}

Answer 2

我会手动放置节点。虽然需要多花点功夫，但我认为结果会更好：

笔记：

• 我添加了clip=false，以便节点的文本不会被切断。

代码：

\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{decorations.markings}
\begin{document}

\begin{tikzpicture}
\begin{axis}[
    compat=newest, 
    height=0.4\textheight,
    enlarge y limits={upper, value=0.3},
    ymin=0,
    xtick=data,
    xtick={\empty},
    ytick=data,
    enlarge x limits = 0.5,
    bar width=24pt,
    title={},
    symbolic x coords={0,5},
    y axis line style={opacity=0},
    yticklabels={\empty},
    ytick style={draw=none},
    axis on top,
    major grid style=white,
    %nodes near coords,
    clip=false
    ]

\addplot [red,  line width=2pt] coordinates {(0,.1) (5,.83)};
\addplot [blue, line width=2pt] coordinates {(0,.12) (5,2.4)};

\node [red,  below left] at (axis cs: 0,.1)  {0.1};
\node [red,  right     ] at (axis cs: 5,.95) {0.83};
\node [blue, above left] at (axis cs: 0,.12) {0.12};
\node [blue, right     ] at (axis cs: 5,2.4) {2.5};

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