[OS X TeX] TKZplot2d for tikz/pgf problem.

Sun May 13 20:27:31 EDT 2007

Hello!

I've recently discovered pgf/tikz and have been impressed with it's  
features and relative ease of use. Being a mathematics teacher, I  
also think the TKZplot2d and other add-ons to tikz found below will  
be very useful.

http://www.altermundus.fr/pages/pdflatex/plot2d.html

If anyone is familiar with this enhancement to pgf/tikz plotting  
package for latex, maybe you can help me with a minor (I think) problem.

I've been trying the example plots in the TKZplot2d documentation and  
all works fine except for a few of the examples. One of the shorter  
ones is:

\begin{tikzpicture}[scale=1.5]
\tkzinit[xmax=1,xstep=0.1,ymax=1,ystep=0.1]
\tkzgrid
\tkzx
\tkzy
\tkzfct[lw=0.8pt](0.00001..1){\x**\x}
% \tkzfctpt[type=$\bullet$](1/(exp(1)),\tkzfcta){A}
% \tkztg[color=blue,lw=.8pt,kr=0.2,kl=0.2]{\tkzfcta}({1/(exp(1))})
\tkztg[color=blue,lw=.8pt,kr=0,kl=1]{\tkzfcta}(1)
\end{tikzpicture}

This compiles fine as shown but doesn't work when the commented lines  
are uncommented (as they are in the original example in the  
documentation). When these lines are uncommented, I get the errors  
below. I suspect the problem is with the "exp(1)" expression but  
don't understand why this evidently worked as documented but doesn't  
work for me.

If anyone else uses this TKZplot2d package, could you try the above  
example and let me know if you get the same errors that I'm getting.

Thanks much,
Gary.
