Multiple Line Graph Maker
What is a Multiple Line Chart?
A multiple line chart is a type of line graph that displays more than two or three lines on a single graph to compare several data sets at once. It’s ideal when you need to track and visualize the behavior of multiple variables over time or across categories — all in one clean, easy-to-read chart.
Each line represents a different data set and is uniquely colored, with a legend to help distinguish between them.
Why Use a Multiple Line Chart?
- Compare several trends side-by-side
- Spot correlations or contrasts between many data sets
- Present complex information in a simple and visual way
- Monitor multiple variables evolving over the same time range
- Save space by displaying all lines in a single chart
Examples of Multiple Line Charts
- Revenue trends from five regions over a year
- Temperature trends across different cities in a week
- Performance of multiple students over various tests
- Website traffic from several sources (e.g., Google, Facebook, Twitter, Direct)
- Departmental expenses in a company over several quarters
- Fitness metrics like speed, heart rate, and elevation from different athletes
