John - Wow as a newbie I was happy to see that you responded, I've been using a lot of your posts in different areas as examples to get up to speed. Thanks.
So I did try playing with the colors but you're right, if you lighten them than you really can't see them very well. But you got me thinking what if I changed the solid line to a dotted line. The post 17114 was very valuable in figuring out how to display dotted lines and how to play with the weight of the line (http://community.qlik.com/forums/t/17114.aspx).
Unfortunetely looks like there is no solution for forcing values to be on top but as you can see below playing with the line properties does help. Thanks again.
