When I type in
(%i1) plot2d(x,[x,-1,1],[gnuplot_preamble,"set zeroaxis lt 8"])$
I didn't get what I want. The axis are not of style lines. Reason:
maxout.gnuplot:
set term windows "Verdana" 15
set zeroaxis lt 8 <---------------- !
set xlabel "x"
set ylabel "x"
set zeroaxis <---------------- !
plot [-1.:1.] '-' notitle with lines lt 3
-1. -1.
-0.98275862068965525 -0.98275862068965525
...
I think my gnuplot_preamble should be the last line in front of plot [-1: ..
to overwrite the default "set zeroaxis".
