Like what it was doing?  I guess, but what that did was look to the limits of 
the plot, x_min and x_max, and draw a line at the origin between them.  But what 
then if someone changes the limits using set() to make them slightly bigger? 
Then that line will not run from one end of the plot to the other.  Using the 
gnuplot command

| +  fputs (plot_stream, "set xzeroaxis linetype -1 linewidth 0.5;\nreplot;\n");

will automatically adjust the length of the axis line.
