Graphs

What are the different graph and their uses?

Pie graph

Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. There are two primary use cases for a pie chart: If you want your audience to have a general sense of the part-to-whole relationship in your data and comparing the precise sizes of the slices is less important.

Bar Graph

Bar graphs are used to compare things between different groups or to track changes over time. Bar graphs are ideal for comparing two or more values, or values over time. Data is displayed either horizontally or vertically. Single bar graphs are used to convey discrete values of an item within a category.

Line Graph

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. Straight-line graphs are used in the research process and the preparation of the government budget.

Scatter Graph

Scatter graphs uses are to observe and show relationships between two numeric variables. The dots in a scatter plot report the values of individual data points and patterns when the data are taken as a whole. A scatter chart works best when comparing large numbers of data points without regard to time. This is a very powerful type of chart and good when you are trying to show the relationship between two variables

Bubble graph

A bubble chart is primarily used to depict and show relationships between numeric variables. The addition of marker size as a dimension allows for the comparison between three variables rather than just two. Bubble charts are often used to present financial data. Different bubble sizes are useful to visually emphasize specific values. 

Area Chart

Area charts are used to represent cumulated totals using numbers or percentages. Use the area chart for showing trends over time among related attributes. Area charts are commonly used to showcase data that depicts a time-series relationship. Information in an area chart is plotted on the x- and y-axis; data values are plotted using data points that are connected using line segments.
