Hi!

So?

Code:
\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{patterns}

\tikzstyle{myxbarlegend}=
[
/pgfplots/legend image code/.code=
	{\draw [##1, line width=0.2pt] 
		(0,-0.5pt) rectangle (3pt,0.5pt) 
		(4.5pt,-0.5pt) rectangle (7.5pt,0.5pt) 
		(9pt,-0.5pt) rectangle (12pt,0.5pt);
	}
]

\begin{document}

\begin{tikzpicture}

\begin{axis}[xbar,enlargelimits=0.15, myxbarlegend]

\addplot
[draw=blue,pattern=horizontal lines light blue]
coordinates
{(10,5) (15,10) (5,15) (24,20) (30,25)};
\addplot
[draw=black,pattern=horizontal lines dark blue]
coordinates
{(3,5) (5,10) (15,15) (20,20) (35,25)};
\legend{nr1,nr2}
\draw[red] (axis cs:10,10) -- (axis cs:10,0);

\end{axis}
\end{tikzpicture}

\end{document}
