gnuplot plots lines too thick for sequence



Hello --

Consider that the last terms of the sequence:



(%i125) yy:makelist(((-1)^(n+1))/n^2,n,1,4000)$

are:
     1         1           1         1           1
-     --------       ,   --------,              - --------        ,
--------        ,     - --------]
  15968016  15976009    15984004  15992001    16000000

don't you think gnuplot plots lines that are way too thick ? I mean,
this is not necessarily maxima-related (but an upstream issue)...

full commands:

(%i124)  xx:makelist(n,n,1,4000)$
(%i125) yy:makelist(((-1)^(n+1))/n^2,n,1,4000)$
(%i126) yf:ev(yy,numer)$
(%i127) plot2d([discrete,xx,yf],[gnuplot_curve_styles,["with points"]])$
