I composed a diagram that takes up the entire sheet of paper in landscape mode, called diagram.tex (compiled it to generate pdf). I'm trying to include that into an article, but only half of it is showing; the bottom half is cut off by the right end of the paper.
I was able to get it in the proper orientation by using
\includegraphics[angle=90]{diagram.pdf}
But because the bottom half of it is cut off, I need some sort of option where I can do something like this:
\includegraphics[angle=90, shift left = 5cm]{diagram.pdf}
to pull the rest of the image left (or up, depending on how you're looking at it).
So how can I move the figure around?
I'm not sure if this is relevant, but I'm using the following documentclass and packages in my paper:
\documentclass[11pt,a4paper,twoside]{article}
\usepackage{tikz, graphicx}
Edit:
This is not an issue with pushing it past the margins. Half of the picture is not on the paper (sort of like if you stuck half of your left hand behind the left side of your monitor). I need to pull the paper left (just like you would shift your hand left to see it).

\includegraphics[width=1\textwidth, angle=90]{...}? – Holene Apr 07 '13 at 08:24width = 1\textwidthwill scale the inputpdfsuch that it actually fits the page. I may misunderstand how your problem really looks like, but to me it sounds like you want to push the left side of thepdfpast the page margins. In my opinion it's better to stay to the margins. Alternatively you could use thePDFpagespackage and include the entire PDF? – Holene Apr 07 '13 at 08:34\hspace{-<some number>in}\includegraphics[angel=90]{...}? Basically this shifts the included picture left by<some number>inch. – Herr K. Apr 07 '13 at 09:03
