A line chart is a series of data points (called “markers”) connected by a single line plotted across an X and Y-axis. Usually, they display the relationship between two or more variables. These lines flow up and down across the plotted graph showing change. They help the viewer visualize trends or changes for multiple groups over the same period of time.

Where to use interactive line charts
Line charts are useful in many different fields. Any time you want to share how different data categories performed over the same period of time, a line chart is ideal. Line charts are used in finance, science, mathematics, marketing, business, and more, and are great for creating WOW moments.
A typical line chart could show the number of visitors to a site or the stock price of a company changing over time. They can display weather patterns in multiple cities in a set time frame. Line charts can illustrate consumer spending habits across multiple months. The possibilities are endless. When using interactive line charts, expect audience engagement and retention to increase.
Line charts work best when comparing a limited number of variables. If there are too many lines running across a plotted graph, the viewer can become overwhelmed and disengaged. Remember to use line charts only if you want to show how values change over time. If you want to show how values differ in different categories, consider using a column chart.
