What type of chart shows trends over time?

A Line Chart is used in Microsoft Excel and other MS Office tools to show how values change over time. It is especially useful for visualizing trends, patterns, or progress across a timeline—such as days, months, or years. In a line chart, data points are connected using straight lines, making it easy to observe increases or decreases over time.

For example, if you are tracking monthly sales, website visitors, or temperature changes, a line chart will clearly show how the values rise or fall across the time period. This is why line charts are popular in reports, dashboards, and business presentations.
