What is a line plot?

A line plot involves the distribution of dots on a number line to represent values from a data set. Each dot aligns with a number in the set. Multiple values of the same number mound on top of one another.

A line plot is a way to visually represent numerical data, including intervals-level data. It shows the occurrence of a value within a data set and is a part of descriptive statistics. A line plot serves the same purpose as a frequency table, which lists the number of times a value appears in a data set. Line plots organize data from a wide range of values.
