What is a line graph?
A line graph is a type of chart that displays data as points connected by straight lines. It's used to show how data changes over time or across a continuous variable.
When should you use a line graph?
Use line graphs to:
• Show changes over time
• Display continuous data
• Show trends and patterns
• Compare multiple datasets
• Enable interpolation and extrapolation
