Best way to approach clickable duplicating lines?

Hi everyone,
I have a basic drawn using PolyLines. At each datapoint, I am planning on having a vertical bar that can be clicked on to display some value associated with that point. For example, let's say I have an array of data that contains the following: { 10, 20, 30, 50, 60, 0, 100 }

There are seven pieces of data, and those will correspond to the seven data points. So there will be seven vertical bars, and when I hover/click over a particular bar, I get the array value associated with that point. I have a good enough idea on how to create both the duplicating lines + event handler using WinForms, but what are the best ways of doing this using WPF?

Thanks!
Kirupa
