What is a line chart?

A line chart connects observations in order, making changes in a measure easy to follow. Time usually runs along the horizontal axis and the value sits on the vertical axis. The connected path directs attention to the pattern between observations: rises, falls, turning points and periods of stability.

When to use it

Use a line chart for revenue, product usage or response times recorded over a meaningful sequence. It is especially useful for following daily or weekly trends. With only a few quarterly or yearly totals, columns can make individual periods easier to compare. Use bars for independent categories such as products or departments.

Design tips

  • Keep dates in chronological order and make the reporting interval clear. Uneven time gaps should have proportionate spacing when elapsed time matters.

  • Use an annotation to explain a meaningful event, such as a launch. A line moving after an event does not, by itself, establish that the event caused the change.

  • Choose a scale that makes the variation legible without exaggerating it. If the baseline is not zero, make the axis range obvious.
