Hi Ivana, I am trying to show the change in rank over time for the attributes rather than the actual value itself (which I could do using line charts). For e.g. when I want to limit the output, I can use the Top N filter, where I do not have to define the rank myself in the datamodel and the Top N filter can determine that based on the metric (count/sum/etc). Similarly, the bump charts could help show the result in terms of change in rank over time.
