There are many types of graphs and charts that are commonly used for showing business reports. These are listed as follows.

Bar Graphs This is a type of chart, which contains labeled horizontal or vertical bars showing a piece of information and an axis. The numbers along the side of bar graph compose the axis. This is also called as a histogram; Bar Graph is useful when there is a numerical comparison.

Example:



Line Graphs Line graphs are use to track changes over the same period of time for more than one group. Line graphs provide a means in which to compare two or more different types of information through showing how they are similar and how they are differ. This is useful when comparisons are needed.

Example:



Pie Charts A pie chart is a type of a circle graph normally used in showcasing a wholesome quantity; we have to show that how this whole quantity is broken into parts. The whole quantity depicts entire sample space and the pieces of pie in the circle graph are called sectors.
