Special design of 3 plots with LaTeX

Question

I wish design 3 plots (A, B and C) in the form of:

------------------------+---------------+
                        |               |
          A             |               |
                        |               |
------------------------+        C      |
                        |               |
          B             |               |
                        |               |
------------------------+---------------+

I am using PGFPLOTS package, I check the groupplot section in the user's guide but I didn't figure out how to deal with this disposition.

This is one solution using Jake suggestion. Clearly you have to eliminate some ticks or to move them on the opposite axis to have a good looking plot

\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[scale only axis,height=5cm,width=7cm,name=first plot,xtick=\empty,]
\addplot {x};
\end{axis}
\begin{axis}[scale only axis,height=5cm,width=7cm,name=second plot,
anchor=north west,at={(first plot.south west)}]
\addplot {x};
\end{axis}
\begin{axis}[scale only axis,height=10cm,width=7cm,name=third plot,
anchor=north west,at={(first plot.north east)}]
\addplot {x};
\end{axis}
\end{tikzpicture}
\end{document}
