How do I scale this tikz graphic I once made? I tried using

Code: Select all

\begin{tikzpicture}[scale=1.5]

but that created spaces and didn't move the text. Thank you.

Code: Select all

\begin{tikzpicture}   
	% Left wall
	\draw[very thick] (0,-.5) -- (0,.5);

	% First spring (s_0)
	\draw (0,0) -- (0+.25,0);
	\draw (0+.375,-.0125) ellipse (1.25mm and 1.25mm)
				(0+.500,-.0125) node [above,outer sep=2pt,name=s0] {$s_{_0}$} ellipse (1.25mm and 1.25mm)
        (0+.625,-.0125) ellipse (1.25mm and 1.25mm);
	\draw (0+.75,0) -- (0+1,0);
  
	% First two masses and two springs (m_1, s_1, m_2, s_2)
	\foreach \x in {1,2} {
		% Mass (it's just a rectangle)
		\draw ((1.75*\x-.75,0) node[draw,rectangle,name=m\x,anchor=west] {$m_{_\x}$};
		
		% Spring (three circles with connecting lines on the ends).
		\draw (1.75*\x,0) -- (1.75*\x+.25,0);
		\draw (1.75*\x+.375,-.0125) ellipse (1.25mm and 1.25mm)

	}
   
   % Ellipses

           (5.625,-.0125) ellipse (1.25mm and 1.25mm);
	\draw (5.75,0) -- (6,0);
  
	% Last mass and spring (m_N, s_N).
	\foreach \x in {1} {
		% Mass (it's just a rectangle)

Use the graphicx package and put your tikzpicture environment inside a \scalebox command:

Code: Select all

\documentclass{article}
\usepackage{graphicx}
\usepackage{tikz}
\begin{document}

\scalebox{1.5}{\begin{tikzpicture}
 % Put your tikz code here
\end{tikzpicture}}

\end{document}

Worked first time.
Thanks.
