LaTeX - picture

Relativne "rychlo" by som potreboval z toho spravit .pdf:

\begin{picture}(200,75)
\put(0,25){\vector(1,0){200}}
\put(25,0){\vector(0,1){75}}
\put(75,22){\line(0,1){6}}
\put(125,22){\line(0,1){6}}
\put(22,50){\line(1,0){6}}
\thicklines
\put(25,25){\line(1,0){50}}
\put(75,50){\line(1,0){50}}
\put(125,25){\line(1,0){72}}
\put(17,50){\makebox(0,0){$1$}}
\put(75,13){\makebox(0,0)[b]{$\pi$}}
\put(125,13){\makebox(0,0)[b]{$2\pi$}}
\put(195,13){\makebox(0,0)[b]{$t$}}
\put(175,60){\makebox(0,0){$g(t)$}}
\end{picture}

Obycajny text prekladam programom pdflatex(linux), ale tento kod mi neprelozi - chyba tam asi nie je lebo som to okopiroval z nejakej prirucky a neviem kde teda moze byt problem.
