Pie charts are circular charts that display the contribution of each category which is represented by a slice. Each and every slice represents a category of data that makes up the whole pie. A pie chart is able to provide information at a glance itself. For example, you can use a pie chart to compare growth areas within a business such as profit and turnover.
A doughnut chart is like a pie chart with a center hole. It encodes the data values into rings divided into segments. For instance, a donut chart can be used to display a survey of book sales in various genres in a bookstore.
A Single Value Pie chart visualizes parts of a single data value. For instance, the Single Value Plot can be used to show the contribution of product categories in Net Sales. See Create Pie Chart walkthrough to learn how to create this chart.
A Multiple Value Pie or Doughnut chart can be used to display various values divided into common parts using a Doughnut or Pie plot. For example, the Doughnut Plot can be used to show the contribution of product categories into Discounts, Returns, and Unit Cost.
