Bar plots

In package pstricks-add (Maybe in a new version of pstrick this plotstyle have been moved to package pstrick) there is a new plotstyle named bar defined. Use this plotstyle a bar chart can be plotted easily. The parameters closely related to this plotstyle includes "barwidth","fillstyle" and so on. The usage of this plotstyle is very simple. Let us learn it by an example.

\usepackage{pstricks}
\usepackage{pstricks-add}
\usepackage{pst-plot}
\begin{document}
  \begin{psgraph}(-1,0)(6,5){5cm}{5cm}
    \savedata{\mydata}[{0,1},{1,3},
      {2,2}{3,4},{4,1},{5,2}]
    \dataplot[linecolor=blue,plotstyle=bar,
      barwidth=0.5cm,fillcolor=red,
      fillstyle= solid]{\mydata}
  \end{psgraph}
\end{document}
