1       use plot(series1)
2       read help page for plot.default if you are plotting simple 
scatterplot
3       pay attention to xlim and ylim parameters for plot formating
4       when you read help page you could also go through other options

plot(series1, ylim=range(c(series1, series2)))

Petr
