Stacked Bar Chart

Understanding Stacked Bar Charts

A stacked bar chart is a sort of bar chart that displays information in a stacked format. Each bar is split into a couple of sections, with each phase representing an exceptional category or subcategory of statistics. The peak of every segment represents the fee of that class or subcategory, and the overall height of the bar represents the total fee of all classes or subcategories blended.

Stacked bar charts are useful when examining the overall price of various categories or subcategories and the relative contribution of every category or subcategory to the whole fee. They are also beneficial for displaying how the entire fee modifications over time, as you can see how the peak of every phase adjusts from one bar to the subsequent.

Types of Stacked Bar Charts

1. Standard Stacked Bar Chart

Stacked Bar Chart

The standard stacked bar chart, also known as a stacked bar graph, extends the standard bar chart from looking at numeric values across one categorical variable to two. Each bar in a standard bar chart is divided into several sub-bars stacked end to end, each corresponding to a level of the second categorical variable.

For example, if you have total production levels and forecasts for a few types of devices: tablets, phones, and laptops. The total production of all devices can be displayed in a standard bar chart. But if you also wanted to understand the breakdown by device, you could morph the traditional bar chart into a stacked one showing the component contribution.

2. Percentage Stacked Bar Chart

Stacked Bar Chart

A per cent stacked bar chart represents the given facts as the proportion of facts that contribute to a total extent in a distinctive category. This kind of chart is beneficial when you want to evaluate the share of different categories for every bar in the chart.

3. Horizontal Stacked Bar Chart

Like the standard bar chart, the bars in a stacked bar chart may be orientated horizontally. This is specifically useful when the class labels are long or if there are numerous categories.

4. 3D Stacked Bar Chart

A stacked bar chart also can be formatted in 3-D. This provides an intense experience to the chart and can make it more visually attractive. However, it's critical to be aware that 3-D charts can distort the records now and then and make it more difficult to examine values correctly.

5. Value annotations

One solution to avoid confusion when comparing sub-bar lengths is to add annotations to each bar that indicate its size. However, this may add visual clutter to your chart, so use caution. Make sure that the stacked bar chart aligns with your primary objectives for the visual representation or consider using a different chart type.

Using Stacked Bars Effectively

A trendy bar chart is used to evaluate numeric values between distinct categorical variable levels. Each degree of the explicit variable is represented via an unmarried bar on the chart, with the duration of every bar indicating a numeric value. A stacked bar chart also serves this cause but with an additional intention.

The stacked bar chart is useful when we want to understand the relative composition of each primary bar based on the levels of a second categorical variable. In this type of chart, each bar comprises several sub-bars, each corresponding to a level of a secondary categorical variable. The total length of each stacked bar remains the same, but now we can see how each secondary group contributed to that total.

Key Characteristics of Stacked Bar Charts

  • Compositional view: They excel at illustrating how character components make up everything in a class. Each bar acts as a container, segmenting into numerous quantities that constitute exceptional information points.
  • Comparative analysis: Comparing the relative sizes of various categories will become convenient with stacked bars. The universal heights of the bars conveniently monitor which categories maintain the most weight.
  • Trend visualisation: Tracking modifications over time may be efficiently executed with stacked bars. Plotting facts for multiple intervals allows you to examine how class composition and relative sizes evolve.

Practical Uses of Stacked Bar Charts

  • Product income: Analyze the sales overall performance of diverse products inside a shop or throughout special timeframes.
  • Department budgets: Visualize the price range allocation for extraordinary departments in an agency, highlighting spending priorities.
  • Survey results: Depict the distribution of responses from a couple of choice surveys, making it easy to understand famous and unpopular choices.
  • Population demographics: Illustrate the population of different nations via age organisation, offering insights into the age shape of each state.

In conclusion, stacked bar charts are useful for evaluating the entire cost of various categories or subcategories. They are clean to read and understand and permit you to see how one-of-a-kind classes or subcategories contribute to the full value. However, they can become visually complex as greater categories or collections are introduced, and it cannot be easy to evaluate the values of character classes or subcategories across distinct bars.
