An Area Chart is similar to a line chart that is connected using line segments. The Area Chart arranges a period horizontally, connects them by line, encodes values into points, and fills the area between the line segments and x-axis with color. An area plot is a good chart option when you want to observe the volume change over a period. It gives the summation of the quantitative data.
A Stacked Area chart is a type of area chart that helps in breaking down data values into subcategories by placing corresponding area subsections on top of each other. The Create Stacked Area Chart walkthrough showcases plotting the Net Sales over a year with stacked areas for each Product Category.
A Percentage Stacked Area chart combines the stacked area and the Percentage axis scale. Apart from showing changes in data values, the chart can also show each subcategory's contribution to a total. The Create Stacked Percent Area Chart walkthrough showcases plotting the percentage share of Product Categories in Net Sales.
A Clustered Area chart is used to break down data values into subcategories for granular analysis. For example, the Clustered Area Chart can be used to depict the total sales changes over a year segregated into clustered areas per product category.
