I've tried copying a pasting code from various examples posted on this site and in the manual, but the graph is never visible.
MWE: (this MWE comes from this posting)
\documentclass[tikz]{standalone}
\usepackage{tkz-fct}
\begin{document}
\begin{tikzpicture}[>=stealth']
\tkzInit[xmin=-15,xmax=25,
ymin=-250,ymax=50,
xstep=5,ystep=50]
\tkzAxeXY
\tkzFct[domain=-10:24,color=blue,very thick,<->]{14*\x-\x**2}
\end{tikzpicture}
\end{document}
Results in:
pdflatex
