Data view for viewing diffs

Question

Hi, I'm wondering if there's any readily available controll which one can use to nicely show the diff between 2 sources of data. I'm thinking of a view 2D view with % of difference on the height, and then element by element comparsion on the width ( kind of like a very long bar chart where each element is probably represented by a pixel or some such ). The number of elements which are getting diffed will be very many. I'd love some suggestions both on if there perhaps is a better way to view the diff, and if there's any readily available control for these sorts of things which I can use ( I didn't seem to find a good match in the designer ). Was a long time since I used C# and this seemed like a great fit :)
