Hi all,

I have a 2 variable graph, prices on left axis, interest rates on the right
axis with years on the bottom.

I would like to add 2 lines without having to draw them:
1) Average interst rate line.
2) Current interest rate line.

How do i do this?? I've tried adding another series with the average
entered into every year but then my actul interest rate line dissappears to
sit at the bottom (i think it thinks it is a price) AHHHHHH

Thanks
