tkz-fct produces no plots, why?

Question

tkz-fct produces no plots, for instance I copied the following code from the manual:
    documentclass{article}
    
    usepackage{color}
    usepackage{tikz}%
    usepackage{tkz-euclide}
    usepackage{tkz-fct} usetkzobj{all}
    
    begin{document}
    begin{tikzpicture}[scale=.5]
    tkzInit[xmax=100,xstep=10,
    ymax=1000000, ystep=100000]
    tkzAxeX[right] tkzAxeY[above]
    tkzGrid tkzFct[color=red,
    domain=0:100]{x**3}
    end{tikzpicture} 
    end{document}

This results in the following picture:

gnuplot --version gives:

gnuplot 4.4 patchlevel 2

Any ideas how to solve the problem?

Alain Matthes · Answer

Your code works:

You need to read your .log file to verify two things:

the path for gnuplot. If the path is fine then you must find a line like gnuplot executed or something like that

if in your .log file, you have something like

file.table not found,

then you need to use the option --shell-escape or write18 in your script for the compilation.

The problem is the same with pgfplots or another package that uses gnuplot.
