What does the "Set Analysis" feature do in Qlik Sense?

Set Analysis is a powerful feature in Qlik Sense that allows users to create specific conditions for data analysis. By defining a scope, users can focus on particular subsets of data, which enhances their ability to perform comparative analysis or isolate certain groups within their dataset. This feature enables more complex queries by allowing you to specify subsets based on certain criteria, such as time periods or categorical distinctions, which can provide deeper insights into trends and behaviors.

For instance, if you want to compare sales figures from this year to last year, Set Analysis enables you to dynamically select and analyze the relevant data without altering your main dataset. This focused approach is especially useful in scenarios where you want to analyze data while ignoring certain irrelevant entries or segments, allowing for a more tailored and effective data exploration experience.

In contrast, the other features described do not align with the core functionality of Set Analysis. Defining aesthetic properties for charts concerns design rather than data selection, automatically categorizing data pertains to initial organization rather than focused analysis, and real-time analysis of live data streams deals with data freshness which is separate from the concept of discriminating within a dataset using Set Analysis.
