How to Create a Stacked Area Chart
A simple area chart is a representation that shows a fluctuating line on a Cartesian plane depicting the increase and decrease of a value. The area under the line is shaded. Similarly, a stacked area chart features not only one but multiple such lines and shaded regions. They are typically used for understanding the component breakdown of a data group. This guide will look at a stepwise tutorial on drawing the same using EdrawMax Online.
2. How to Create a Stacked Area Chart
Creating stacked area charts is usually required when we need to represent a particular value that is made up of different components and elements. Unlike overlapping area charts, the baseline for each shaded region is not the x-axis. Instead, the start of every part is taken from the region's point before it comes to an end. To understand this better, take a look at the below screenshot. The baseline for the red area is the x-axis. Thereafter, the base edge of the blue region will be taken as where the top of the red part is ending.
1. Note the total
It should be understood that the height of the top-most section represents the total value of the data. Once you are done making the chart, you have to check and see if the total conforms to the point where the end of the line is meeting. If it's not, you have probably erred somewhere when entering the values. Thus, it is essential to note the total before you begin the work for this double-checking.
2. Create a legend
As with many other similar graphs and charts, the distinguishing feature between the different regions is the color used to shade them. Be sure to add a legible key/legend to your work to help the reader understand it better. With area charts in general, the key is provided below the figure.
3. Pay attention to the order
When making a stacked chart with EdrawMax Online, you have to enter the particulars via a spreadsheet (more on this later). You should take special care to start with the smallest values and then work up to the higher ones. If you accidentally add a smaller region after a larger one, it will still show up, but the color will be affected.

4. Expert Tips for Making Stacked Area Chart
Use your colors wisely
Whenever you have to distinguish between different sections or regions, use contrasting and vivid colors to help the reader make the differences.
Limit the number of sections
Remember, it's a stacked area chart, not a rainbow. Stacked charts are good for showing 4-5 sections. Any more than that could be a bit too complex.
Pay attention to the labels
During the whole coloring and shading process, you could lose sight of the chart for reading. The numbers, as well as the texts on both axes, should be appropriately sized and spaced.
