Add the code to your path and then type pretty before plotting and they become much easier to read.

pro pretty
loadct,39,/silent
device,decomposed=0
!p.font=1
!p.charsize=4
!p.color=cgcolor('black')
!p.background=cgcolor('white')
!x.thick=3
!y.thick=3
!x.margin*=0.8
!p.thick=2
plotsym,0,/fill
end
Much better! If, for whatever reason, you want to undo the pretty plot just use "cleanplot.pro" which resets everything.
