Hi there

I would like to plot multiple lines on a graph, but often these lines overlap, in which case Stata (quite understandably) obscures one line with another.
Can anyone suggest some good techniques for slightly displacing the overlapping lines so that they are all visible? I recognise that any displacement would make it look as though one rate is higher/lower than another (when they are, in fact, the same), but I'm fine with that.

Below is an example.

With thanks

Code:
clear
input int year float(rate1 rate2 rate3 rate4)
1999 2 2 12 12
2000 3 3 13 13
2001 4 4 14 14
2002 5 5 15 15
2003 6 6 16 16
2004 7 7 17 17
2005 8 8 18 18
end
line rate1 rate2 rate3 rate4 year, yscale(range(0, .1 )) ylabel(#5)
