I am relatively new to LaTeX and I was playing around with figures and came across the scalebox command. This apparently lets you scale a graph that you create or import into your LaTeX document by a certain amount. How do you know how much scalebox will scale your figure by? I read somewhere that typing \scalebox{0.5} scales a graph to 0.8 times the original size. Is there any way to figure out what fraction of the original size your graph will become?

I don't think I have a full answer but I found myself with a similar problem one day and solved it using bold versions of smaller fonts. For som fonts it works and for some it doesn't. This is where you skill and taste comes into effect. Here is my case where I think it works: (the \hskips are cause it's an abbreviation)
\documentclass[12pt]{memoir}
\usepackage[osf]{mathpazo}
\begin{document}
\newcommand{\inchi}{%
\mbox{\textsc{i}%
\hskip 0.1 em {\scriptsize \textbf{n}}%
\hskip 0.1 em {\normalsize \textsc{c}}%
\hskip 0.1 em {\scriptsize \textbf{h}}%
\hskip 0.1 em {\normalsize \textsc{i}}%
}
}
Lorem ipsum \inchi dolor\ldots
\end{document}
For the sizes, you can use the current bounding box together with \pgfgetlastxy:
\documentclass{standalone}
\usepackage{tikz}
\newcommand*{\ExtractCoordinate}[3]{\path (#1); \pgfgetlastxy{#2}{#3};}%
\newdimen\tlx
\newdimen\tlx
\newdimen\brx
\newdimen\bry
\begin{document}
\begin{tikzpicture}
\draw (-3,-1) rectangle (3,1) (-2,-2) rectangle (2,2);
\foreach \x in {north west,south west,south east,north east}
{ \fill[red] (current bounding box.\x) circle (0.01);
}
\ExtractCoordinate{current bounding box.north west}{\tlx}{\tly}
\ExtractCoordinate{current bounding box.south east}{\brx}{\bry}
\pgfmathsetmacro{\myheight}{(+\tly-\bry)/28.452755}
\pgfmathsetmacro{\mywidth}{(-\tlx+\brx)/28.452755}
\node[below right] at (-2,1) {height: \myheight\ cm};
\node[above left] at (2,-1) {width: \mywidth\ cm};
\end{tikzpicture}
\end{document}
Edit 1: Ah, now I get it. Here is a still not automatic version. You set two commands in each tikzpicture:
\maximumdimensions{4}{3}, which is the desired width and height, at the beginning of the picture.
\getscalingfactors which will draw nodes with a recommended scaling factor in the middle of your picture if the image if to high/wide:
\documentclass{scrartcl}
\usepackage{tikz}
\usepackage{lipsum}
\usepackage{xifthen}
\newcommand*{\ExtractCoordinate}[3]{\path (#1); \pgfgetlastxy{#2}{#3};}%
\newdimen\tlx
\newdimen\tlx
\newdimen\brx
\newdimen\bry
\def\xscalefactor{}
\def\yscalefactor{}
\parindent0mm
\newcommand{\getscalingfactors}{%
\ExtractCoordinate{current bounding box.north west}{\tlx}{\tly}
\ExtractCoordinate{current bounding box.south east}{\brx}{\bry}
\pgfmathsetmacro{\myheight}{(+\tly-\bry)/28.452755}
\pgfmathsetmacro{\mywidth}{(-\tlx+\brx)/28.452755}
\pgfmathsetmacro{\xsf}{\maxwidth/\mywidth}
\pgfmathsetmacro{\ysf}{\maxheight/\myheight}
\global\edef\xscalefactor{\xsf}
\global\edef\yscalefactor{\ysf}
\pgfmathtruncatemacro{\xsfc}{\xsf*10000}
\pgfmathtruncatemacro{\ysfc}{\ysf*10000}
\ifthenelse{\xsfc > 10000}{}{\node[fill=white,above] at (current bounding box.center) {x-s: \xsf};}
\ifthenelse{\ysfc > 10000}{}{\node[fill=white,below] at (current bounding box.center) {y-s: \ysf};}
}
\newcommand{\maximumdimensions}[2]{% width, height
\global\edef\maxwidth{#1} % in cm
\global\edef\maxheight{#2} % in cm
}
\begin{document}
\begin{tikzpicture}[scale=1]
\maximumdimensions{4}{3}
\draw[fill=orange] (-3,-1) rectangle (3,1) (-2,-2) rectangle (2,2);
\getscalingfactors
\end{tikzpicture}
\lipsum[1]
\begin{tikzpicture}[scale=1]
\maximumdimensions{4}{3}
\draw[fill=orange!50!gray] (0,0) circle (3);
\draw[fill=red!50!gray] (3,1) circle (1);
\draw[fill=blue!50!gray] (-2,2) circle (1);
\draw[fill=green!50!gray] (-3,-2) circle (1);
\draw[fill=yellow!50!gray] (2,-1) circle (1);
\getscalingfactors
\end{tikzpicture}
\end{document}
If you scale the picture down enough, the nodes inside the picture vanish:
\begin{tikzpicture}[scale=0.66] and \begin{tikzpicture}[scale=0.497]

It is not true that
\scalebox{0.5}of thegraphicspackage scales a graph to 0.8 times of the original size. It scales it simply by this factor, as Ian Thompson already said in his answer.Note that their is also
\resizebox{<width>}{<height>}{<content>}which allows you to scale the image to a given size. This can be more useful for adjusting bigger graphics or pictures:\resizebox{\textwidth}{!}{<content>}scales the content directly to the size of the main text. The!for the height states that it should scale with the width. See my answer to Quickest way to include graphics for more explanation about scale vs. direct width/height.See the
graphics/xmanual for the other commands like\rotatebox. Note that if you want to resize images you can use the optional arguments of\includegraphics[height=<height>,width=<width>,angle=<angle>,keepaspectratio]{<filename>}.For other things like diagrams drawn using TeX commands (
pgf/tikz,pstricks, etc.) there is theadjustboxpackage which gives you\adjustbox{height=<height>,width=<width>,angle=<angle>,keepaspectratio}{<TeX content>}or the similar and very newgincltexwhich allows you to include.texfiles like images using\includegraphics.
