QlikView extensions and the cycle plot

If we are going to work with advanced data visualization in QlikView, we have to get used to working with extensions. We can either develop the QlikView extension ourselves or use open source extensions that are available in Qlik Branch (http://branch.qlik.com).

For example, we are presented with the challenge to find a better way to visualize year-over-year (YoY), week-over-week (WoW), or any other period-over-period analysis. The following line chart demonstrates how difficult it can be to compare a large number of periods:
