Question

How to choose proper graphs (pie chart, bar chart, and histograms)?

Answer 1

To choose proper graphs (pie chart, bar chart, and histograms), following requirements of the graphs are seen :-

1. If we want to understand the distribution of the data-

Distribution charts help us to understand outliers, the normal tendency, and the range of information in your values.

Use Bar charts to show distribution.

2. If we want to compare values-

Pie Charts are perfect for comparing one or many value sets, and they can easily show the low and high values in the data sets. To create a comparison chart, use these types of graphs:

3. If we want to show the composition of something-

Use this type of chart to show how individual parts make up the whole of something, such as the device type used for mobile visitors to our website or total sales broken down by sales rep.

To show composition, use these charts:

• Pie
• Stacked Bar

4.If we want to know the underlying frequency distribution (shape) of a set of continuous data-

A histogram is a plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. This allows the inspection of the data for its underlying distribution (e.g., normal distribution), outliers, skewness, etc.
