### PST/PSTricks not working at all

Hi !

I'm using MiKTeX compiler and Visual Studio Code as my editor. I tried to plot a function using PSTricks but I always get fatal errors even when copying the exact same code as written on my manual book (LaTeX for teachers, Ellipses). So I create a empty document and add some code found on the web ([url="https://tug.org/PSTricks/pst-plot/Examples-exa/fixPoint0.pdf"]this pdf[/url]) to try understand what's going wrong but it fails too. Here's the code I use from the pdf linked before :

\documentclass[11pt]{article} % Packages\usepackage[utf8]{inputenc}    % support for accents\usepackage[T1]{fontenc}\usepackage[francais]{babel}   % doc language\usepackage{lmodern}\usepackage[a4paper]{geometry} % marges\usepackage{amssymb}\usepackage{amsmath}           % Text into equation\usepackage{pstricks-add} \begin{document} \psset{unit=2cm}\begin{pspicture}(-2.5,-1.5)(2.5,2.5)    \psaxes{->}(0,0)(-2.5,-1.5)(2.5,2.5)    \psplot[linewidth=1.5pt,algebraic]{-2.5}{+2.5}{(2*x+4)/(2+x^2)}    \psline[linestyle=dashed](-1.5,-1.5)(2.5,2.5)    \def\function{ xVal dup add 4 add xVal dup mul 2 add div }%    \pstVerb{ /xVal -1 def }% start value    \multido{\nA=0+1}{10}{%        \psline[linestyle=dotted](! xVal 0 )(! xVal xVal)        \psline[linecolor=red](! xVal xVal )(! xVal \function )        \psline[linecolor=red](! xVal \function )(! \function\space dup)        \pstVerb{ /xVal \function\space def}    }\end{pspicture} \end{document}

On the \psplot, \psline and \def\function commands I get the following errors :
Undefined control sequence.\c@lor@to@ps ->\PSTricks Undefined control sequence.\XC@usec@lor ...string \color@ #1#2\endcsname \@@

Every other example of PST code I use gives me the same errors. I don't understand what's going wrong and why it works for everyone and not me... Can you help me please !
Thanks !

PS : When I delete everything in the pspicture environment except from the \psaxes line, I got something strange : numbers are displayed but no line nor arrow at all !

You have to use LaTeX in dvi mode, or use XeLaTeX.

You cannot use pdfLaTeX to generate a pdf directly if you want to work with pstricks.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.
