A Line Graph is considered as a higher form of Chart. Commonly used in many scientific fields (usually, those dealing with large quantities of numbers and those involving time), Line Graph is created by connecting series of points that represent individual measurements with line segments.

Line Charts are often used to present data trends that are in time intervals, thus the lines found in it are chronological in order.

Line Graphs are good in summarizing how two information (or sets of data) are related and how they vary depending on one another.

Line Graphs are also popular in the experimental sciences because of the following reasons: a Line Graph is a good way to show specific values of data, it shows trends (in data) clearly, and it enables viewers to make predictions about the results of data that are not yet recorded.

Scatter Plots are related to Line Graphs. They have the same features as that of Line Graphs; the only difference between the two is that, Scatter Plots does not use lines to visualize data. Usually, in Scatter Plots, a dot or small circle represents a single data point. The trends in this type of Chart can be derived by how tight the dots cluster together.

A common variation of Line Graph is the Multiple Line Graph. This type of Graph is used to illustrate the trends of two or more independent variables.The most favorable characteristic of a Multiple Line Graph is that it saves space, if compared to the usual Bar Graph.
