%This is the way to redefine styles
% \newpsstyle{mytickstyle}{linewidth=1pt,linecolor=blue}
%
% Style of the foreground frame
\newpsstyle{diagframestyle}{linewidth=1pt,linecolor=black,fillcolor=white}
% Style of the background frame
\newpsstyle{diagbgframestyle}{linewidth=1pt,linecolor=black,fillcolor=yellow}

% Use 3D bars
\renewcommand{\ActiveBarPrimitive}{\barTDRect}
% Make frame 3D
\renewcommand{\frameTD}{1}

% Put ticks and levellines each 10 yunits
\renewcommand{\betweenticks}{10}

% Color of the numbers on the bar-items 
\renewcommand\numbercolor{\white\bf}
% Where to put the number. Can be \bottom,\belowtop,\overtop
\renewcommand{\placenumber}{\bottom}


% override the default \tdx and \tdy
\renewcommand{\tdx}{1.2} % depth of 3d
\renewcommand{\tdy}{6}

% Start the diagram
\bardiagrambegin{14}{100}{3cm}{1}{5}{0.8cm}{0.1cm}
% To draw ``years'' at 45 degrees
