节点作为标签的相对定位

节点作为标签的相对定位

我正在使用节点作为图表上的标签，但它们重叠的问题。我知道我可以手动移动它们，但这将是更大文档的一部分，该文档将为许多指标生成相同的图表，并且每个标签的相对位置可能不同。有没有办法编写这个，以便它根据需要移动每个图表的标签节点？出于空间考虑，我希望它们向左/向右移动，而不是向上/向下移动。

  • 百分比是否可能相等或非常接近？我建议旋转 30°

  • 用于节点的垂直对齐 \vphantom{bp}

您已经手动定位了文本。因此，我只需在需要的地方添加“左”或“右”选项：

\documentclass[12pt]{article}
\usepackage{tikz}
\definecolor{RYGgreen}{RGB}{143,185,53}
\definecolor{RYGyellow}{RGB}{230,226,46}
\definecolor{RYGred}{RGB}{230,71,71}

% goals
\newcommand\NormalGoal{0.9}
\newcommand\NormalGoalWarning{0.91}
\newcommand\CurrentMeasureValue{0.7127625}
\newcommand\PreviousMeasureValue{0.653847}

\newcommand\PercentValue{}
\newcommand\PercentWithDecimal[2]{%
    \pgfmathparse{100*#1}%
    \pgfmathprintnumberto[precision=#2]{\pgfmathresult}{\PercentValue}%
    \PercentValue\%%
}

\begin{document}
    \begin{center}
        \begin{tikzpicture}[
  arr/.style args = {#1/#2}{draw=#2, line width=#1}, 
every node/.style = {text height=2ex, text depth=0.5ex, 
                     inner xsep=0pt, text=black}% normal goal
                           ]
            % draw line
\draw[arr=5pt/RYGred] (0,0) node[left] {0\%}-- (14,0); % not meeting goal
\draw[arr=5pt/RYGyellow](14*\NormalGoal,0) -- (14,0); % warning zone
\draw[arr=5pt/RYGgreen](14*\NormalGoalWarning,0) -- (14,0) node[right] {100\%}; % meeting
            % draw goal marker
\draw[arr=2pt/black]   
    (14*\NormalGoal,-0.5) node[below] {90\%} --  
    (14*\NormalGoal,0.5)  node[above] {goal};
            % current value line
\draw[arr=2pt/RYGred] 
    (14*\CurrentMeasureValue, -0.5) node[below right] {\PercentWithDecimal{\CurrentMeasureValue}{2}} -- 
    (14*\CurrentMeasureValue,0.5)   node[above right] {current}; %
            % previous measurement period value line
\draw[arr=2pt/gray] 
    (14*\PreviousMeasureValue, -0.5) node[below left] {\PercentWithDecimal{\PreviousMeasureValue}{2}} --
    (14*\PreviousMeasureValue,0.5)   node[above left] {previous}; %
        \end{tikzpicture}
    \end{center}
\end{document}

正如您所看到的，我还自由地定义了线条和节点的样式，从而可以编写更短的图像代码。
