Dan, Another tweak ! If you want the 'legend' to look pretty you can resize it by adding,say, 'cex=0.6' into the legend code; try--- legend("topleft", #inset=-1, legend = do.call("expression", L), bg='white', ncol = 2, pch=c('','','',':',':',':'), x.intersp = 0.4, title="Yay! Thank You!", cex=0.6 ) John
