Area Chart
An area chart is a type of graph that is used to display quantitative data over a set period of time. It is similar to a line chart, but the area between the line and the x-axis is filled with color, making it easier to visualize the magnitude of the values over time. Area charts are commonly used to show the trend of values over time and to compare the values of different categories.
Key Features of Area Charts
- X-Axis: The horizontal axis represents the categories or time periods.
- Y-Axis: The vertical axis represents the quantitative values being measured.
- Area Fill: The area between the line and the x-axis is filled with color to represent the magnitude of the values.
- Multiple Series: Area charts can display multiple data series, allowing for easy comparison.
- Stacked Area Chart: In a stacked area chart, the different data series are stacked on top of each other, showing the total magnitude as well as the individual contributions.
Advantages of Area Charts
- Visualizing Trends: Area charts make it easy to visualize the trend of values over time.
- Comparing Categories: They allow for easy comparison of values across different categories.
- Highlighting Magnitude: The filled area helps to highlight the magnitude of the values.
How to Create an Area Chart
- Collect your quantitative data and organize it by categories or time periods.
- Choose a suitable tool or software to create the area chart, such as Microsoft Excel, Google Sheets, or other data visualization platforms.
- Enter your data into the charting tool and select the area chart type.
- Customize the chart by adding axis labels, titles, and colors to make it visually appealing and easy to understand.
- Review and analyze the area chart to draw insights from the data.
Study Guide
If you are studying area charts, here are some key points to focus on:
- Understand the purpose and use of area charts.
- Learn how to read and interpret area charts, including understanding the x-axis, y-axis, and area fill.
- Practice creating area charts using different sets of data to understand their application in real-world scenarios.
- Compare area charts with other types of graphs, such as line charts and bar charts, to understand when to use each type of visualization.
- Explore advanced variations of area charts, such as stacked area charts, and understand their significance in data analysis.
By mastering the concept of area charts, you will be able to effectively visualize and analyze quantitative data, making informed decisions based on trends and comparisons.

The resources above cover the following skills:
Geometry (NCTM)
Use visualization, spatial reasoning, and geometric modeling to solve problems.
Use geometric models to represent and explain numerical and algebraic relationships.
Measurement (NCTM)
Apply appropriate techniques, tools, and formulas to determine measurements.
Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.
Develop and use formulas to determine the circumference of circles and the area of triangles, parallelograms, trapezoids, and circles and develop strategies to find the area of more-complex shapes.
Connections to the Grade 6 Focal Points (NCTM)
Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
