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?

Answer 1

Your code works:

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

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

2. 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.
