[Tex/LaTex] Boxplot in LaTeX

boxplotpgfplotstikz-pgf

I am new to LaTeX. How can I draw a boxplot in LaTeX. My data set is as below

index median box_top box_bottom whisker_top whisker_bottom
0 1 1.2 0.4 1.5 0.2
1 2 2.3 1.5 2.7 1
2 0.7 1.4 0.5 1.9 0.1

I am using Kile on Ubuntu 12.04 LTS.

EDIT: Code is added with output.

    \documentclass{minimal}
    \usepackage{pgfplots}
    \usepackage{filecontents}

    \begin{filecontents}{testdata.dat}
     0 1 1.2 0.4 1.5 0.2
     1 2 2.3 1.5 2.7 1
     2 0.7 1.4 0.5 1.9 0.1
     3 1 1.2 0.4 1.5 0.2
     4 2 2.3 1.5 2.7 1
     5 0.7 1.4 0.5 1.9 0.1
    \end{filecontents}

    \pgfplotsset{
     box plot width/.initial=1em,
     box plot/.style={
        /pgfplots/.cd,
        black,
        only marks,
        mark=-,
        mark size=\pgfkeysvalueof{/pgfplots/box plot width},
        /pgfplots/error bars/.cd,
        y dir=plus,
        y explicit,
     },
     box plot box/.style={

        },
        /pgfplots/table/.cd,
        y index=2,
        y error expr={\thisrowno{3}-\thisrowno{2}},
        /pgfplots/box plot
     },
     box plot top whisker/.style={

            {\pgfplotserrorbarsmark}%
            \pgfkeysgetvalue{/pgfplots/error bars/error mark options}%
            {\pgfplotserrorbarsmarkopts}%
            \path ##1 -- ##2;
        },
        /pgfplots/table/.cd,
        y index=4,
        y error expr={\thisrowno{2}-\thisrowno{4}},
        /pgfplots/box plot
     },
     box plot bottom whisker/.style={
        /pgfplots/error bars/draw error bar/.code 2 args={%
            \pgfkeysgetvalue{/pgfplots/error bars/error mark}%
            {\pgfplotserrorbarsmark}%
            \pgfkeysgetvalue{/pgfplots/error bars/error mark options}%
            {\pgfplotserrorbarsmarkopts}%
            \path ##1 -- ##2;
        },
        /pgfplots/table/.cd,
        y index=5,
        y error expr={\thisrowno{3}-\thisrowno{5}},
        /pgfplots/box plot
     },
     box plot median/.style={
        /pgfplots/box plot
     }
    }

    \begin{document}
    \begin{tikzpicture}
    \begin{axis} [enlarge x limits=0.5,xtick=data, box plot width=0.5em]
     \addplot [box plot median] table {testdata.dat};
     \addplot [box plot box] table {testdata.dat};
     \addplot [box plot top whisker] table {testdata.dat};
     \addplot [box plot bottom whisker] table {testdata.dat};
    \end{axis}
    \end{tikzpicture}
    \end{document}

EDIT 2: here is the actual data I am trying to plot

%index median box_top box_bottom whisker_top whisker_bottom
0.52 21.5 191.5 4 150842.5 3
0.53 17 71.5 3 30840.5 2
0.54 5 1 2 2799 1
0.55 9 54 3 2425 2
0.56 4 11.5 2 643.5 1
0.57 3 10 2 124 1

Boxplots are described in chapter 5.9.1 of the PGFPLOTS manual. [EDIT chapter 5.12.1 as of pgfplots v. 1.13]

Using your data with the examples in the manual I get:

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\usepgfplotslibrary{statistics}
\begin{document}

\begin{tikzpicture}
  \begin{axis}
    [
    ytick={1,2,3},
    yticklabels={Index 0, Index 1, Index 2},
    ]
    \addplot+[
    boxplot prepared={
      median=1,
      upper quartile=1.2,
      lower quartile=0.4,
      upper whisker=1.5,
      lower whisker=0.2
    },
    ] coordinates {};
    \addplot+[
    boxplot prepared={
      median=2,
      upper quartile=2.3,
      lower quartile=1.5,
      upper whisker=2.7,
      lower whisker=1
    },
    ] coordinates {};
    \addplot+[
    boxplot prepared={
      median=0.7,
      upper quartile=1.4,
      lower quartile=0.5,
      upper whisker=1.9,
      lower whisker=0.1
    },
    ] coordinates {};
  \end{axis}
\end{tikzpicture}

\end{document}
