Hi there, I would like to make a 'bumps chart' like the ones described e.g. here: http://junkcharts.typepad.com/junk_charts/bumps_chart/ Purpose: I'd like to plot the proportion of people in select countries living for less then one USD pr day in 1994 and 2004 respectively. I have already constructed a barplot - but I think a bumps chart would be better # The barplot and data countries <- c("U-lande", "Afrika syd for sahara", "Europa og Centralasien", "Lantinamerika og Caribien","Mellem?stenog Nordafrika", "Sydasien","?Stasien og stillehaveet", "Kina", "Brasilien") poor_1990 <- c(28.7,46.7,0.5,10.2,2.3,43,29.8,33,14) poor_2004 <- c(18.1,41.1,0.9,8.6,1.5,30.8,9.1,9.9,7.5) poor <- cbind(poor_1990,poor_2004) rownames(poor) <- countries oldpar <- par(no.readonly=T) par <- par(mar=c(15,5,5,1)) png("poor.png") par <- par(mar=c(15,5,5,1)) barplot(t(poor[order(poor[,2]),]),beside=T,col=c(1,2),las=3,ylab="% poor",main="Percent living for < 1 USD per day (1993 prices)",ylim=c(0,50)) legend("topleft",c("1990","2004"),fill=c(1,2),bty="n") par(oldpar) dev.off() I Guess I need to start with an normal plot? Something like the below - but there is a loong way to go... # A meager start - how to finish my bumps chart plot(c(rep(1,9),rep(2,9)),c(fattig_1990,fattig_2004),type="b",ann=F) Thankfull for any help. Cheers. Andreas
