wxplots



Hi Andrej,

I have noticed, that for embedded wxplots the default is "set zeroaxis;", even if I hadn't 
chosen this option.

So I had to do
(%i3) wxplot2d([x^2], [x,-5,5],
 [gnuplot_preamble, "unset zeroaxis;"])$
to get a plot without axis. 

With 
(%i4) plot2d([x^2], [x,-5,5],
 [plot_format, gnuplot])$ 
there is no axis. 

I would prefer to have no axis as the default, because it is very easy to add one with the 
help of the plot dialog window. 

Thanks for always improving your great software.
