Line Graphs

03 min read

Line graphs (also called Cartesian graphs) indicates the variation of a quantity with respect to another quantity. Line graphs are usually used for presentation of continuous data or information.  It is easy to interpret from line graphs. But it’s difficult to interpret the data accurately.

Types of Line Graphs:

Single dependent variable graph:

A single dependent variable is plotted against the independent variable.

 

More than one dependent variable graph:

The number of dependent variables is more than one and the vertical scale is common to all the variables.

Graphs having 2 scales:

Here 2 scales are drawn, one on the lleft-hand side and the other on the right-hand side corresponding to two variables.
