There are many ways to visualize data, but some methods are better than others, depending on the type and amount of data you have. When you have a lot of data, a stacked chart is a great way to show all of the information while still being able to see patterns. Keep reading to learn how to interpret a stacked chart.
What is a stacked chart?
A stacked chart is a graph in which data is displayed as bars, with each bar representing a different category and the total of all the bars for a given type represented by the height of the bar. The advantage of using a stacked chart is that it allows you to compare the relative sizes of different categories at a glance. For example, if you want to compare the market shares of two companies, you can use a stacked chart to display them side-by-side.
The central stack in a stacked chart is the vertical column representing the total value of all the data series in the chart. The main stack is always located on the right side of the chart, and it always has a height that corresponds to the total value of all the data series. The central stack can be used to determine how much of the total value is represented by each data series.
To interpret data from a stacked chart, start by looking at the overall trend. In most cases, you’ll want to focus on the direction of the most significant category first and then look at trends for smaller categories afterward. If you’re looking at market share data, for example, you would want to focus on whether or not one company’s market share is growing or shrinking compared to the other company’s market share. Once you’ve identified any trends, try to identify any outliers or points that don’t seem to fit with the rest of the data. Finally, always be sure to read any accompanying notes or labels that explain what specific values correspond to each bar on the graph.
What are the different types of stacked charts?
A stacked chart is a way of representing data in which each “slice” of the pie is a different category, and the size of the slice reflects the relative magnitude of that category within the whole. There are three types of stacked charts: column, bar, and area. Column and bar charts are very similar, except that column charts use vertical bars to represent data while bar charts use horizontal bars. Area charts are similar to column and bar charts, but instead of using bars, they use shaded areas to represent data.
A stacked column chart is a graph that displays data as stacked columns. Each column represents a different category, and the height of each column reflects the value for that category. The total size of the stack represents the total value for all types. To interpret a stacked column chart, first look at the full height of the pile. This indicates the total value for all categories. Then, look at each individual column to see how it contributes to the overall total. Finally, look at how each category’s value compares to the others.
All three types of stacked charts can be used to compare values between different categories. For example, you could use a column chart to compare sales figures for other products over time. This type of chart can also be used to identify trends or patterns in one or both of the measures being tracked. Or you could use an area chart to compare market shares for different companies in a particular industry.
