Dear Richie, Unfortunately that doesn't help because it requires you to know beforehand what sort of graph you're generating. I want to be able to generate a graph (irrespective of the type) and then use a common process to label them so I don't have to think about which way I generated the graph to start with...

(or is there an easier way to go about this?) The easier way: use win.metafile to save your plots, e.g. win.metafile("base.emf") plot(runif(50)) mtext("labelling text",outer=TRUE,at=0.5,adj=0.5,line=-1.1,side=1,cex=0.7,col="darkgrey") dev.off() win.metafile("grid.emf") xyplot(runif(50)~1:50) grid.text("labelling text",x=0.5,y=0.005,just="bottom",gp=gpar(fontsize=8, col="darkgrey")) dev.off() Regards, Richie.
