Interpolate curve through two lists

Hi,

I would like to draw a curve through a series of points that are on two separate lists. What is the best way to combine these two lists? I’ve tried merge and weave but did not work.

I think either Weave or otherwise Pick’N’Choose are the ones you want. I attached a file that shows the difference.
