Which chart type is used to show information that changes over time?

Showing information that changes over time needs a format that clearly traces how values move from one moment to the next. Line graphs do this by plotting each measurement along a time-based horizontal axis and then connecting the points with a line. That line reveals trends—whether numbers rise, fall, or stay steady—so you can see the overall pattern as time progresses. Bar graphs focus on comparing separate categories at a single point, which makes them less ideal for showing continuous change over time. Line plots or dot plots present individual data points but don’t usually connect them to illustrate a progression. A generic term like charts/graphs is too broad to specifically convey how data evolves over time.
