Hi list. I'm plotting pluviometric (Rain) data as a barplot, and then adding the salinity variable to this plot as lines. Obviously as these Y scales are completely different the salinity appears at the lower part of the graph extremely compacted. I need to plot the line at the exactly same area of the barplot but with its own Y axis (at the right), so the salinity can use the plot area freely. I tried the par(new=T), but it only works for high level plot functions (not for lines or points).
Below are some example data and the code I'm using: Month Rain Salt Fev 365.6 13 Mar 235 18 Abr 115.1 18 Mai 47.4 18.75 Jun 112 15 Jul 156.8 17 Ago 66.1 15 Set 149.8 14 Out 167.1 11.5 Nov 269.3 17.5 mp<-barplot(Dados$Rain,names.arg=rownames(Dados),ylab='Pluviosidade (mm)',width=0.5,ylim=c(0,370),yaxp=c(0,370,10)) lines(mp,Dados$Salt,type='b',pch=19,lty='dotted') Any ideas? Thank you for the attention. Regards ------------------------------------------------------------------- MSc.
