What Is a Combination Chart and How Do You Create an Effective One?

Charts are essential tools for visualizing data and providing insights that can be difficult to comprehend with mere numbers. But, not all charts are created equal. Some offer more power, versatility, and clarity, one of them is a combination chart. It is this ability to convey complex relationships, trends, and comparisons in an understandable format that makes the combination chart extremely valuable. Keep reading to learn more about what is a combination chart and how it is used in analysis.

Understanding the Basics of Combination Charts


At its core, a combination chart is a visual representation that integrates two or more types of charts into one, like a line graph and a bar chart. This synergy gives you the ability to represent different kinds of data simultaneously.

The effectiveness of a combination chart lies in its ability to present complementary data in a way that makes the data more meaningful, adding a depth of understanding that is usually unavailable with a single chart.

For instance, on a combination chart, you can display revenue (bar chart) and percent growth (line chart) simultaneously. This integration provides an impactful, cohesive view of the data.

Knowing when and how to use a combination chart, therefore, requires an understanding of the kind of data you want to visualize and the relationships you want to highlight.

Reasons Why Combination Charts are Used in Analysis

Combo charts are particularly useful when you need to visualize data that have different scales or units, as they can effectively display disparate measures on different axes.

They’re also great tools for performing comparative analysis. For example, it’s easier to compare data series side by side using bars and noting trends or patterns using lines in the same chart.

Furthermore, combo charts make it possible to visualize complex relationships between data, facilitating easier interpretation and rapid insights.

Lastly, combo charts, by visualizing multiple measurements, can provide a comprehensive, single view of the data, rendering it a valuable tool for data analysts and decision-makers.

The Key Elements of an Effective Combination Chart

An effective combo chart has a clear purpose, is clean and uncluttered, and is easy to read at a glance. Its elements include a clear and informative title, legends for different data sets, primary and secondary axes, and clear data points.

The title of your combo chart should clearly state what the chart is displaying. It gives the viewer an introductory insight into what they should expect from the chart.

Legends are essential to distinguish between different data types in your chart. The primary and secondary axes should be clearly labeled with appropriate scales to avoid any confusion.

Lastly, the data points should be marked clearly and consistently across the chart, enabling viewers to quickly and accurately interpret the information displayed.

Recognizing When to Use a Combination Chart

The decision to use a combination chart largely depends on the data you want to visualize. While combination charts are great tools, they are not always the best choice.

A combination chart is best used when you want to compare values or show different types of other related information. So, when you want to look at how two sets of data correlate or to identify any emerging trends and patterns, a combination chart can be most effective.

If you’re trying to show causation or the relationship between different sets of data, a combination chart could be your go-to option. The ability to draw a line and a bar on the same chart makes it easier to see such relationships. However, if the data you want to visualize doesn’t require comparisons or doesn’t possess any significant relationships, a different chart type might be more suitable.

Altogether, the ability to grasp complex data sets via combination charts is a profoundly powerful tool that aids data-driven decisions in various industries. Therefore mastering the art of creating these charts is an invaluable skill for analysts and data enthusiasts.
