# Choosing location of legend entries in Pgfplots

I am fairly new to using pgfplots and have been combing the manual for a couple hours now and I can't find an elegant solution to my problem. I would like to have two columns of legend entries and then one "label" underneath them all and centered. I managed to get it by playing with the [text width= ] settings, but I was wondering if there was a better way. MWE:

\documentclass[11pt,titlepage]{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.10,
height=0.5\textwidth,
width=0.8\textwidth,
every axis/.append style={thick}}
\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}[
legend pos=north west,
legend columns=2,
scaled y ticks = false,
xlabel={Months},
ylabel={Profit},
yticklabel={\\$ \pgfmathprintnumber{\tick} },
ymin={-5500},
xmin={0},
xmax={5.5},
ytick={-5500, 0, 5000, 10000, 15000},
xtick={1,2,...,5},
grid=major,
]
\addplot[mark=none, color=red, domain=0:5.5] {900*x -5200};
\addplot[mark=none, color=green, domain=0:5.5] {1900*x -5200};
\addplot[mark=none, color=blue, domain=0:5.5] {2900*x -5200};
\addplot[mark=none, color=orange, domain=0:5.5] {3900*x -5200};
\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}

btw, is there a less annoying way to insert code than to go add 4 spaces to each line? – JayCle Apr 26 '14 at 14:37
If you are using Emacs with AUCTeX, you can hit tab and it will indent the line to the appropriate level. I imagine other editors do the same (at least that would be nice). – dustin Apr 26 '14 at 14:40
@JayCle: A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). Or just highlight and press "CTRL-K"... – Christian Hupfer Apr 26 '14 at 14:40
@ChristianHupfer he meant on the forum. I thought in his editor to achieve the indentation. My mistake. – dustin Apr 26 '14 at 14:42
@dustin: No problem at all ;-) – Christian Hupfer Apr 26 '14 at 14:44
