  • First you have to reset the margin so that the figure can fit the page. Secondly, use figure environment with centering.

Your graphics are too large to be centered. To see this, simply load the showframe package that highlights the page and its margins.



It is therefore necessary to reduce the graph!
I know two different ways to reduce it:




  • with Tikz scale=.5, transform shape

  • with the macro scalebox

    fill   = gray!50,

    draw   = black,

    thick,

    minimum height = 1cm,

    minimum width  = 1cm

}}



tikzset{circlenode/.style = {

    shape  = circle,

    fill   = blue!20,

    draw   = blue,

    thick,

    minimum size = 1cm

}}

    By default, enlargements and reductions do not affect the nodes, they only affect the coordinates. However, your graph is built with nodes, transform shape also allows you to make scale act on the nodes.

    • I understand the key scale. What is the purpose of transform shape in Tikz

      By default, enlargements and reductions do not affect the nodes, they only affect the coordinates. However, your graph is built with nodes, transform shape also allows you to make scale act on the nodes.

    Your graphics are too large to be centered. To see this, simply load the showframe package that highlights the page and its margins.



    It is therefore necessary to reduce the graph!
    I know two different ways to reduce it:




    • with Tikz scale=.5, transform shape

    • with the macro scalebox

      By default, enlargements and reductions do not affect the nodes, they only affect the coordinates. However, your graph is built with nodes, transform shape also allows you to make scale act on the nodes.
