Line Graphs
Line graphs display data points connected by a line. They may include a single line to represent one category within the data set or multiple lines to represent more than one category. They are best used to illustrate patterns or trends over time.
Multiple Line Example
When to Use
- When illustrating a trend or pattern is important or helpful
- Use multiple lines to compare trends between two or more categories
Variations
- Multiple Line Example (shown above)
- Single Line Example
- Sparkline Example
Variations
Single Line Graphs
Use single line graphs to display the relationship between two data measurements in a single line. For example, to display profits over time.
Sparklines
Sparklines are simplified line graphs used to quickly convey trends and fluctuations in a more abstract manner. They are best used in small spaces and when detailed numerical data is not required.
