Mekko Chart is similar to the stack bar chart but additionally it shows the relativity among the different stack categories with the increased or decreased width. This will help in identifying the strongness or weakness of a particular category.
In this video I've explained about the type of data that is required to create a Mekko chart and creation of Mekko chart from the scratch with some of its important properties.
I hope you'll find this video useful and an addition to your existing learning of QlikView.
