AFAIK you need to adjust xlim and ylim in first call of plot as the plot 
itself is not redrawn but you only add points (or other graphing objects 
like lines) to existing plot. If you know what you want to plot you can 
use xlim=range(all.values.you.want.to.plot) for "automatic" adjustment of 
plotting area during first plot call.
