我如何调整 y 轴的值？

Question

我对此图的 y 轴值感到困惑。我不知道如何调整 y 轴值以使图更“放松”（我不知道如何解释）

代码如下

     \documentclass[12pt,a4paper]{article}
          \usepackage[a4paper, margin = 1 in]{geometry}
          \usepackage[spanish, es-tabla]{babel}
           \usepackage[utf8]{inputenc}
         \usepackage{pgfplots}
         \usepackage{tikz}
    \begin{document}
                  \begin{tikzpicture}
                    \begin{axis}[


                     title = {Gráfico de Sedimentación},
                        %scale only axis,
                        axis lines = left,
                        xlabel = {Número de componente},
                        ylabel = {Autovalor},
                        xmin=0, xmax=5,
                        ymin=0, ymax=4,
                        xtick={1,2,3,4,5},
                        ytick={3.395,1.059,0.410,0.110,0.027},
                        yticklabel style={/pgf/number format/.cd,fixed,precision=3},
                        ymajorgrids=true,
                        grid style = dashed,
                    ]

                    \addplot[
                        color=black,
                        mark = *,
                        ]
                        coordinates {(1,3.395) (2,1.059) (3,0.410) (4,0.110) (5, 0.027)};

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

我会将其制作成对数图。

\documentclass[12pt,a4paper]{article}
\usepackage[a4paper, margin = 1 in]{geometry}
\usepackage[spanish, es-tabla]{babel}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[ymode=log,
   title = {Gr\'afico de Sedimentaci\'on},
      %scale only axis,
      axis lines = left,
      xlabel = {N\'umero de componente},
      ylabel = {Autovalor},
      xmin=0, xmax=5,
      ymin=0, ymax=4,
      xtick={1,2,3,4,5},
      ytick={3.395,1.059,0.410,0.110,0.027},
      yticklabels={3.395,1.059,0.410,0.110,0.027},
      yticklabel style={/pgf/number format/.cd,fixed,precision=3},
      ymajorgrids=true,
      grid style = dashed,
      ylabel style={yshift=1em}
  ]

  \addplot[
      color=black,
      mark = *,
      ]
      coordinates {(1,3.395) (2,1.059) (3,0.410) (4,0.110) (5, 0.027)};

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

或者，如果您想保留您的图，请使用nodes near coords。

\documentclass[12pt,a4paper]{article}
\usepackage[a4paper, margin = 1 in]{geometry}
\usepackage[spanish, es-tabla]{babel}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[%ymode=log,
   title = {Gr\'afico de Sedimentaci\'on},
      %scale only axis,
      axis lines = left,
      xlabel = {N\'umero de componente},
      ylabel = {Autovalor},
      xmin=0, xmax=5,
      ymin=0, ymax=4,
      xtick={1,2,3,4,5},
      ytick={3.395,1.059,0.410,0.110,0.027},
      yticklabels={},
      yticklabel style={/pgf/number format/.cd,fixed,precision=3},
      ymajorgrids=true,
      grid style = dashed,
      ylabel style={yshift=1em},
      nodes near coords
  ]

  \addplot[
      color=black,
      mark = *,
      ]
      coordinates {(1,3.395) (2,1.059) (3,0.410) (4,0.110) (5, 0.027)};

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