# Installing GNUplot [closed]

I would like to run this program but my output is only the axes themselves! I thought my MiKTeX console updates all softwares for my TeXnicCenter platform but apparently not since when I run this:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
% use GNUplot (avaiable in TeXLive)
\draw[->] (-4.5,0) -- (4.5,0) node[below] {$x$};
\draw[->] (0,-4.5) -- (0,4.5) node[left] {$y$};

\draw[blue,thick] plot[raw gnuplot,smooth] function {
f(x,y) = x*y*y+2*(x**3)*(y**3)-y-1;
set xrange [-4:4];
set yrange [-4:4];
set view 0,0;
set isosample 500,500;
set cont base;
set cntrparam levels incre 0,0.1,0;
unset surface;
splot f(x,y);
};
\node[below=5mm,blue] at (current bounding box.south)
{The curve $xy^2+2x^3y^3=y+1$.};
\end{tikzpicture}
\end{document}


My Output is without plot:

• Although tikz provides gnuplot facilities or uses gnuplot, the installation of gnuplot is not really on-topic on TeX.SE. There is nothing difficult on selecting https://sourceforge.net/projects/gnuplot/files/gnuplot/5.2.6/gp526-win64-mingw_2.exe/download and download and run the self-extracting document. – user31729 Jan 27 at 15:15
• Can you run gnuplot from the command line? – Jesse op den Brouw Jan 27 at 15:40
• You have to run pdflatex with the option shell-escape otherwise it is not allowed to run an external program from within a pdflatex run – user2478 Jan 27 at 15:47
