I am trying to draw a tree in LaTeX via following code. It works; however, it is always aligned to the left. How I can make it aligned to the centre?

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{forest}

forestset{.style={for tree={parent anchor=south, child anchor=north,align=center,inner sep=2pt}}}



begin{forest}

[TP

    [DP [D\the] [NP [N\man ]]]

    [T'

        [T\will ]

        [VP

            [V\eat ]

                [DP [D\a ] [NP [N\burger ]]]

        ]

    ]

]

end{forest}

Note: The code is taken from https://msu.edu/~amunn/latex/sharelatex-trees-forest-v1.pdf (Link deprecated; new version here)

align=center only centres text within nodes. It does not centre the forest relative to the page.

A more fundamental problem is that the settings in .style will not be applied with current Forest. To see this, try adding, blue and notice that your tree stays determinedly black.

Current Forest provides default preamble instead.

documentclass{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage{forest}

forestset{default preamble={for tree={blue,parent anchor=children, child anchor=parent,align=center,inner sep=2pt}}}

begin{document}

begin{center}

  begin{forest}

    [TP

        [DP [D\the] [NP [N\man ]]]

        [T'

            [T\will ]

            [VP

                [V\eat ]

                    [DP [D\a ] [NP [N\burger ]]]

            ]

        ]

    ]

  end{forest}

end{center}



end{document}

Obviously, you should delete the blue in your real document.

You might, however, want to use

usepackage[linguistics]{forest}

instead which will apply a nice (for linguistics!) set of defaults to your trees without your having to specify them.

documentclass{article}

usepackage[T1]{fontenc}

usepackage[utf8]{inputenc}

usepackage[linguistics]{forest}

% forestset{default preamble={for tree={blue,parent anchor=children, child anchor=parent,align=center,inner sep=2pt}}}

begin{document}

begin{center}

  begin{forest}

    [TP

        [DP [D\the] [NP [N\man ]]]

        [T'

            [T\will ]

            [VP

                [V\eat ]

                    [DP [D\a ] [NP [N\burger ]]]

            ]

        ]

    ]

  end{forest}

end{center}



end{document}
