Hi,
I have a problem when I want to put a legend on the graph.
I do:

legend("topright", names(o), cex=0.9, col=plot_colors,lty=1:5, bty="n")

but the legend is writen into the graph (graphs' top but into the graph),
because I have values on this position. How can I write the legend on top
the graph without the legend writes on graph's values.

Thanks.
