Area Chart or Area Graph is utilized to display quantitative data in a graphical manner. Common uses include the comparison of two or more quantities. Area Charts can be utilized to represent cumulated totals using numbers or percentages over time.
Use the Area Chart type to show trends over time among related attributes. When multiple attributes are included, the first attribute is plotted as a line with a color fill followed by the second attribute, and so on. Technically, this chart type is based on the Line Chart and represents a filled area between the zero line and the line that connects data points.
The area can be filled with a color, texture (image), or hatch fill. The same as for Line Charts, timeline scale is the most common case for the X-axis in Area Charts, but sometimes ordinal scale can also be used.
