Created using R version 2.14.1 (2011-12-22) with the following script: code

#!/usr/bin/Rscript
svg(bg = "transparent");
par(mar=c(4,6,1,1));
curve(2-cos(x * pi/180)+12*cos(x * pi/180)^2, 0, 180, 
      xlab = expression(phi*group("[",deg,"]")), 
      ylab = expression({}^3*J[HH]*group("[",Hz,"]")), 
      bty = 'l', lab = c(6,10,5), 
      xaxs = "i", yaxs = "i", ylim = c(0,16));
