I have not seen your sample for AI2 yet.
If you want that specific chart type, I would try this for a Canvas-based solution:
- Match up your list of countries and their old/new ranks against a list of colors
- Derive the y coordinates of the various colored lines based on Canvas1.Height and your list lengths
- Draw the texts for your countries and their old and new values above the colored lines
- Draw the colored lines on the left and right
- Plot sections of sine curves to bridge the colored lines across the gaps. Sine curves have flat sections at +/- 90 degrees that could be used to link up to the left and right colored line segments, given a proper displacement and multiplier factor.
