Best Examples Of Stacked Bar Charts For Data Visualization
Data visualization is becoming more important as metrics are needed for everything from customer conversions to the current bounce rate. Data visualization allows for data to be organized in an easier to understand format. The wide variety of graphs and charting styles allows for any problem to be solved and any kind of data to be charted. Choosing the wrong kind of chart for the data you have available can also cause confusion on what you are trying to communicate with the presented data.
Since this data is often used in decision-making it is important to choose the right chart type for visualization so that wrong decisions aren’t made based on bad interpretation of the data. Bar charts are used for representing categorical comparisons or for trending data over time. These simple charts allow for an instant understanding of changes over time in a specific category.
In contrast, stacked bars allow you so view several data sets to be stacked on top of each other, each whole bar represent a certain volume. They show how a complete category is broken up into segments and the relationship these individual segments have on the total whole or amount.
For example, if you wanted to chart the population of students in each of the three seventh grade classrooms in a school and wanted to further break down the classes by gender, three bars would stand next to each other, while each individual bar would be broken into two segments – one for girls and one for boys – within the individual bar.
Thus, every bar would represent the entire class population and each segment within the bar would represent amount of boys vs girls are in the class. Creating effective stacked bar charts can be a little confusing, but when well executed they allow you to clearly visualize comparison and trending. Using clear chart design principles can help you created an effective stacked bar charts that are cognitively friendly and allow for the max amount of view comprehension.
