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
