When to use a line chart
A line chart is useful for showing how values change over time or sequence, such as daily traffic, monthly revenue, weight records, price movement, temperature, or project progress. It helps reveal trends, turning points, and unusual changes.
The horizontal axis should usually have a clear order, such as dates, months, or stages. If the data is only category comparison, a bar chart is often easier to read.
Formula or logic
- X-axis: date, time, or ordered items
- Y-axis: the value being tracked
- Adjacent data points are connected to show change
Example
To view 30 days of website visits, use dates as labels and visits as values. The line chart will show peaks, dips, and overall direction.
Common questions
Is a line chart good for category data?
Only if the categories have a meaningful order. Otherwise, a bar chart is usually clearer.
Can I use a line chart with few data points?
Yes, but trend interpretation is limited when there are very few points.
Can it show growth trends?
Yes. It is useful for spotting increases, decreases, stable periods, and fluctuations.
