If I try this example with just 40 points instead of 4000, the plot
has no lines, but a set of plus signs at the expected points.  With
4000 points, all you see is 4000 plus signs crammed into a small
space.  I don't see how you would expect anything else.  Try the same
thing, but remove the gnuplot_curve_styles and you'll get a thin line.
