[edit] Summary

See How to create graphs for Wikipedia articles

I made it with the following Gnuplot code:


# set the output
set terminal svg enhanced size 1000 1000 fname "Times" fsize 25
set output "Spherical_bessel_y_plot.svg"

set title "Spherical Bessel function, second kind"

# axis properties
set xzeroaxis linetype -1 linewidth 0.5
set yzeroaxis linetype -1 linewidth 0.5
set xrange [0:15]
set yrange [-1.5:0.7]
set xlabel "x"
set ylabel "y_n (x)"
plot -cos(x)/x ti "n = 0" with lines linewidth 2,\
     -cos(x)/x**2 - sin(x)/x ti "n = 1" with lines linewidth 2,\
     (-3/x**2 + 1)*cos(x)/x - 3*sin(x)/x**2 ti "n = 2" with lines linewidth 2

Then I postprocessed with Inkscape.
