Stacked bar charts are a type of bar chart that displays the sum of multiple values by stacking them vertically. They are a popular way to visualize data, as they can easily show the relative contributions of different categories to a total value.
However, stacked bar charts also have some disadvantages. One disadvantage is that they can be difficult to read when there are many categories, as the bars can become cluttered and difficult to distinguish.
In this article, we will discuss the advantages and disadvantages of stacked bar charts in more detail. We will also provide some tips for creating effective stacked bar charts.
Stacked bar chart disadvantages and advantages doc
Stacked bar charts are a popular data visualization technique, but they have both advantages and disadvantages.
- Easy to compare categories
- Show relative contributions
- Can be difficult to read with many categories
- Bars can be cluttered and difficult to distinguish
- Not suitable for comparing individual values
- Can be misleading if categories are not mutually exclusive
- Use consistent colors and labels
- Limit the number of categories
By following these tips, you can create effective stacked bar charts that communicate your data clearly and concisely.
Easy to compare categories
One of the main advantages of stacked bar charts is that they make it easy to compare the values of different categories. This is because the bars are stacked on top of each other, so you can see the relative sizes of the categories at a glance.
For example, the following stacked bar chart shows the sales of different products in a store. You can easily see that Product A is the best-selling product, followed by Product B and Product C.

Overall, stacked bar charts are a great way to compare the values of different categories, both in terms of their relative sizes and over time.
However, it is important to note that stacked bar charts can be difficult to read when there are many categories. This is because the bars can become cluttered and difficult to distinguish. In these cases, it may be better to use a different type of chart, such as a grouped bar chart or a line chart.
Show relative contributions
Another advantage of stacked bar charts is that they can show the relative contributions of different categories to a total value. This is because the height of each bar represents the total value of the category, and the height of each segment within the bar represents the contribution of that segment to the total.
For example, the following stacked bar chart shows the sales of different products in a store, broken down by region. You can easily see that the North region is the largest contributor to total sales, followed by the South region and the East region.

Stacked bar charts can also be used to show the relative contributions of different categories to a total value over time. For example, the following stacked bar chart shows the number of visitors to a website over the past few months, broken down by traffic source. You can easily see that organic search is the largest contributor to website traffic, followed by social media and direct traffic.

Overall, stacked bar charts are a great way to show the relative contributions of different categories to a total value, both in terms of their overall contribution and over time.
However, it is important to note that stacked bar charts can be difficult to read when there are many categories or segments. This is because the bars and segments can become cluttered and difficult to distinguish. In these cases, it may be better to use a different type of chart, such as a grouped bar chart or a pie chart.
Can be difficult to read with many categories
One of the main disadvantages of stacked bar charts is that they can be difficult to read when there are many categories. This is because the bars can become cluttered and difficult to distinguish, especially if the categories are similar in size.
- Overlapping bars
When there are many categories, the bars in a stacked bar chart can overlap, making it difficult to see the individual values for each category.
- Cluttered appearance
A stacked bar chart with many categories can appear cluttered and busy, making it difficult to interpret the data.
- Difficult to compare categories
When there are many categories, it can be difficult to compare the values of different categories, as the bars may be too small or too close together to see the differences clearly.
- Misleading data representation
In some cases, a stacked bar chart with many categories can misrepresent the data. For example, if one category is much larger than the others, it may appear to dominate the chart, even though the other categories may be significant.
To avoid these problems, it is important to limit the number of categories in a stacked bar chart. If there are too many categories, it may be better to use a different type of chart, such as a grouped bar chart or a pie chart.
Bars can be cluttered and difficult to distinguish
Another disadvantage of stacked bar charts is that the bars can be cluttered and difficult to distinguish, especially when there are many categories or segments.
- Overlapping bars
When there are many categories or segments, the bars in a stacked bar chart can overlap, making it difficult to see the individual values for each category or segment.
- Small bar segments
When there are many categories or segments, the segments within each bar can be very small, making it difficult to see the differences between them.
- Similar colors
If the colors used for the different categories or segments are too similar, it can be difficult to distinguish between them, especially if the bars are small or cluttered.
- Lack of white space
If there is not enough white space between the bars or segments, the chart can appear cluttered and busy, making it difficult to interpret the data.
To avoid these problems, it is important to use a limited number of categories or segments, and to choose colors that are distinct and easy to distinguish. It is also important to use white space effectively to separate the bars and segments, and to make sure that the bars are large enough to be easily seen.
Not suitable for comparing individual values
Stacked bar charts are not suitable for comparing the individual values of different categories. This is because the height of each bar represents the total value of the category, and the height of each segment within the bar represents the contribution of that segment to the total. This makes it difficult to see the individual values of the categories, especially if the categories are similar in size.
For example, the following stacked bar chart shows the sales of different products in a store. You can easily see that Product A is the best-selling product, followed by Product B and Product C. However, you cannot easily see the individual sales of each product.
[Image of a stacked bar chart showing the sales of different products in a store]
To compare the individual values of different categories, it is better to use a different type of chart, such as a grouped bar chart or a line chart.
Grouped bar charts show the values of different categories side by side, making it easy to compare them. For example, the following grouped bar chart shows the sales of different products in a store.
[Image of a grouped bar chart showing the sales of different products in a store]
Line charts show the values of different categories over time, making it easy to see how the values have changed. For example, the following line chart shows the sales of different products in a store over time.
[Image of a line chart showing the sales of different products in a store over time]
Overall, stacked bar charts are not suitable for comparing the individual values of different categories. It is better to use a different type of chart, such as a grouped bar chart or a line chart, for this purpose.
Can be misleading if categories are not mutually exclusive
Stacked bar charts can be misleading if the categories are not mutually exclusive. This means that some of the data may be counted in more than one category, which can inflate the total value of the chart.
- Overlapping data
When the categories in a stacked bar chart are not mutually exclusive, some of the data may be counted in more than one category. This can lead to overlapping data, which can inflate the total value of the chart.
- Misrepresentation of data
If the categories in a stacked bar chart are not mutually exclusive, the chart may misrepresent the data. For example, if one category is much larger than the others, it may appear to dominate the chart, even though the other categories may be significant.
- Difficult to interpret data
When the categories in a stacked bar chart are not mutually exclusive, it can be difficult to interpret the data. This is because it is not clear which data points belong to which categories.
- Inaccurate conclusions
If a stacked bar chart is used to make conclusions about the data, and the categories are not mutually exclusive, the conclusions may be inaccurate. This is because the chart may not be accurately representing the data.
To avoid these problems, it is important to make sure that the categories in a stacked bar chart are mutually exclusive. This means that each data point should belong to only one category.
Use consistent colors and labels
When creating a stacked bar chart, it is important to use consistent colors and labels to make the chart easy to read and understand.
Consistent colors
Use consistent colors to represent the different categories in your chart. This will help to make the chart visually appealing and easier to understand. For example, you could use a different color for each product category in a chart showing sales data.
Consistent labels
Use consistent labels to describe the different categories in your chart. This will help to make the chart clear and concise. For example, you could use the same label for each product category in a chart showing sales data.
Benefits of using consistent colors and labels
- Improved readability
Using consistent colors and labels makes your chart easier to read and understand. This is because readers can quickly identify the different categories and their values.
- Increased clarity
Consistent colors and labels make your chart more clear and concise. This is because readers can easily see the relationships between the different categories.
- Enhanced visual appeal
Using a variety of colors can make your chart more visually appealing. This can help to engage readers and make them more likely to pay attention to your data.
By following these tips, you can create stacked bar charts that are easy to read, understand, and visually appealing.
Limit the number of categories
One of the best ways to avoid the problems associated with stacked bar charts is to limit the number of categories. This will make the chart easier to read and understand, and it will also reduce the chances of the bars becoming cluttered or difficult to distinguish.
- Improved readability
Limiting the number of categories makes your chart easier to read and understand. This is because readers can more easily identify the different categories and their values.
- Reduced clutter
When you limit the number of categories, there is less data to display on the chart. This reduces the chances of the bars becoming cluttered or difficult to distinguish.
- Easier to compare categories
When there are fewer categories, it is easier to compare the values of different categories. This is because the bars are more spread out and there is more space between them.
- More effective communication
By limiting the number of categories, you can make your chart more effective at communicating your message. This is because readers are more likely to understand and remember the information in your chart.
As a general rule, you should limit the number of categories in a stacked bar chart to 5-7. However, you may need to use more categories if the data is complex or if you need to show a lot of detail.
