What is the primary purpose of a line chart in Qlik Sense?

A line chart in Qlik Sense is designed primarily to display trends or changes in data over time. This visualization is particularly effective for representing continuous data, allowing users to easily identify patterns, fluctuations, and trends across a timeline. When data points are plotted on the chart, the connecting lines help in visualizing how values evolve, making it simple to observe increases or decreases over specific intervals, such as days, months, or years.

While other chart types serve different purposes—for instance, comparing different data sets, illustrating relationships between variables, or showcasing categorical data—the line chart's strength lies in its ability to convey temporal dynamics. This makes it a preferred choice when the goal is to analyze how a particular measure varies through time. Thus, the functionality and design of a line chart in Qlik Sense align closely with the requirement to visualize trends effectively.
