# Feynman Diagrams with jaxodraw-2.1-0

My problem is that once I run pdflatex in a file with the code exported by jaxodraw, I only got the labels and any diagram.

This is my .tex file:

\documentclass[a4paper]{article}
\usepackage{axodraw4j}
\usepackage{pstricks}
\usepackage{color}

\setlength{\oddsidemargin}{0pt}
\setlength{\evensidemargin}{0pt}
\setlength{\topmargin}{0pt}
\setlength{\topskip}{0pt}
\setlength{\footskip}{0pt}
\setlength{\textwidth}{\paperwidth}
\setlength{\textheight}{\paperheight}

\pagestyle{empty}
