Centralizando a figura do gráfico do grupo

Question

Alguém pode me mostrar como centralizar isso group plot? Eu tentei todos os truques do livro tex.stackexchange de postagens semelhantes (por exemplo,Como centralizar figuras grandes no LaTeX e como corrigir linhas curtas justificadas?).

\documentclass[]{article}
    \usepackage{pgfplots, alphalph}
    \usepgfplotslibrary{groupplots}

\begin{document}

\begin{figure}
    \begin{tikzpicture}[font=\footnotesize\sffamily]
      \begin{groupplot}[
         group style={group size=3 by 2, vertical sep=70pt,
    ylabels at=edge left
    },
          view={0}{90},
          width=5.2cm,
          height=5.2cm,
      scale only axis,
      scaled ticks = false,
      tick label style={/pgf/number format/fixed},
      title={My title},
      xlabel={x-axis},
      ylabel={y-axis}],
          unbounded coords=jump]
        ]
        \nextgroupplot [title={\it{Title 1}}]       
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 2}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 3}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 4}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 5}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

         \end{groupplot}

    \end{tikzpicture}
  \end{figure}

Seus enredos são muito amplos. Você pode tentar colocar 2 parcelas seguidas em vez de 3. No entanto, sempre há técnicas de caixa que podem ser usadas.

\documentclass[]{article}
    \usepackage{pgfplots, alphalph}
    \usepgfplotslibrary{groupplots}

\begin{document}

\begin{figure}
\makebox[\textwidth]{%
    \begin{tikzpicture}[font=\footnotesize\sffamily]
      \begin{groupplot}[
         group style={group size=3 by 2, vertical sep=70pt,
    ylabels at=edge left
    },
          view={0}{90},
          width=5.2cm,
          height=5.2cm,
      scale only axis,
      scaled ticks = false,
      tick label style={/pgf/number format/fixed},
      title={My title},
      xlabel={x-axis},
      ylabel={y-axis}],
          unbounded coords=jump]
        ]
        \nextgroupplot [title={\it{Title 1}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 2}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 3}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 4}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 5}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

         \end{groupplot}

    \end{tikzpicture}
    }
  \end{figure}

Se for o caso, você deseja centralizar os dois últimos gráficos, você pode usar uma largura adequada para todos os gráficos (para saber quanto deslocar) e usar xshiftcomo

\nextgroupplot [xshift=1.2in,title={\it{Title 4}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [xshift=1.2in,title={\it{Title 5}}]
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

Com table:

\documentclass[]{article}
    \usepackage{pgfplots, alphalph}
    \usepgfplotslibrary{groupplots}
\usepackage{filecontents}
 \begin{filecontents*}{mydata.dat}
  A   B      
  1    4
  2    6
  3    9
  4    2
  5    3
  \end{filecontents*}

\begin{document}

\begin{figure}
\makebox[\textwidth]{%
    \begin{tikzpicture}[font=\footnotesize\sffamily]
      \begin{groupplot}[
         group style={group size=3 by 2, vertical sep=70pt,
    ylabels at=edge left
    },
          view={0}{90},
          width=5.2cm,
          height=5.2cm,
      scale only axis,
      scaled ticks = false,
      tick label style={/pgf/number format/fixed},
      title={My title},
      xlabel={x-axis},
      ylabel={y-axis}],
          unbounded coords=jump]
        ]
        \nextgroupplot [title={\it{Title 1}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

        \nextgroupplot [title={\it{Title 2}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

        \nextgroupplot [title={\it{Title 3}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

        \nextgroupplot [title={\it{Title 4}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

        \nextgroupplot [title={\it{Title 5}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

         \end{groupplot}

    \end{tikzpicture}
    }
  \end{figure}




\end{document}

e com

        \nextgroupplot [xshift=1.2in,title={\it{Title 4}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

        \nextgroupplot [xshift=1.2in,title={\it{Title 5}}]
\addplot[black, thick, mark=o, only marks]
    table[x=A,y=B]{mydata.dat};

Answer 2

Outra alternativa: adicionar \hspace*{-4cm}(ajuste quantos centímetros deseja para conseguir uma boa centralização). Por exemplo:

\documentclass[]{article}
    \usepackage{pgfplots, alphalph}
    \usepgfplotslibrary{groupplots}

\begin{document}

\begin{figure}
\hspace*{-4cm}
    \begin{tikzpicture}[font=\footnotesize\sffamily]
      \begin{groupplot}[
         group style={group size=3 by 2, vertical sep=70pt,
    ylabels at=edge left
    },
          view={0}{90},
          width=5.2cm,
          height=5.2cm,
      scale only axis,
      scaled ticks = false,
      tick label style={/pgf/number format/fixed},
      title={My title},
      xlabel={x-axis},
      ylabel={y-axis}],
          unbounded coords=jump]
        ]
        \nextgroupplot [title={\it{Title 1}}]       
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 2}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 3}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 4}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

        \nextgroupplot [title={\it{Title 5}}]      
\addplot[black, thick, mark=o, only marks]
    coordinates {
        };

         \end{groupplot}

    \end{tikzpicture}
  \end{figure}
