What is an area chart?
An area chart is a graphical representation of a data set where the area between a series of data points and a horizontal line is filled in with color or shading. This type of chart is often used to visualize changes over time.
How do you create an area chart?
There are a few things to keep in mind when creating an area chart. First, the data should be displayed in chronological order, with the earliest data point on the left and the most recent data point on the right. Second, the data should be displayed as a series, with each data point representing a single point in time. Finally, the area between each data point and the horizontal line should be filled in with the same color or shading.
There are a few different ways to create an area chart in Excel. You can use the Insert > Area Chart menu, or you can use the following shortcut:

How do you interpret an area chart?
There are a few things to consider when interpreting an area chart:
The scale of the y-axis. The y-axis should be scaled so that the largest value is at the top of the chart, and the smallest value is at the bottom. This will ensure that the data is correctly represented and that the reader can easily compare values.
The color of the rectangles. The color of the rectangles can be used to indicate the value of the data point. For example, a blue rectangle might represent a value of 10, while a red rectangle might represent a value of 100.
The size of the rectangles. The size of the rectangles can be used to indicate the value of the data point. For example, a large rectangle might represent a value of 100, while a small rectangle might represent a value of 10.
The width of the rectangles. The width of the rectangles can be used to indicate the value of the data point. For example, a wide rectangle might represent a value of 100, while a thin rectangle might represent a value of 10.
The position of the rectangles. The position of the rectangles can be used to indicate the value of the data point. For example, a rectangle that is positioned at the top of the chart might represent a value of 10, while a rectangle that is positioned at the bottom of the chart might represent a value of 100.
Overall, area charts are a great way to visualize data.
