Which Chart Type Is Best When You Want to Chart Two Unrelated Data Type?


Scott Campbell

When it comes to charting two unrelated data types, choosing the right chart type is crucial. You want to present your data in a clear and visually engaging way that allows viewers to easily understand the relationship between the two data sets. In this article, we will explore different chart types and their suitability for charting unrelated data types.

Bar Chart

A bar chart is an excellent choice when you have two unrelated data types that you want to compare. The horizontal bars make it easy to visually compare the values of each data set. You can use different colors or patterns for each data set to further enhance the distinction.


  • Data Set A: Sales Revenue
  • Data Set B: Website Traffic

Note: Make sure both data sets are on the same scale for accurate comparison.

Scatter Plot

If you want to identify any potential correlation or relationship between two unrelated data types, a scatter plot is a great choice. Each point represents a pair of values from the two data sets, allowing you to visually analyze any patterns or trends.

  • Data Set A: Temperature
  • Data Set B: Ice Cream Sales

Note: Plotting a large number of points may result in overcrowding, so consider using transparency or reducing point size if needed.

Pie Chart with Subcategories

If you want to show how each part contributes to the whole while comparing unrelated data types, a pie chart with subcategories can be effective. Each slice represents a percentage of the total, and subcategories within each slice provide further breakdown.

  • Data Set A: Expenses
  • Data Set B: Revenue

Note: Limit the number of subcategories to maintain clarity and avoid overcrowding the chart.

Line Chart

A line chart is suitable when you want to track the trends or changes over time for two unrelated data types. The lines represent the values, and by plotting them over time, you can easily visualize any patterns or fluctuations.

  • Data Set A: Stock Prices
  • Data Set B: Exchange Rates

Note: Ensure that time intervals are evenly spaced for accurate interpretation of the data.

Radar Chart

A radar chart is a unique choice for comparing multiple data sets with different variables. Each variable is represented by a spoke, and the length of each spoke corresponds to the value of that variable. This chart type allows you to compare unrelated data types across multiple categories simultaneously.

  • Data Set A: Performance Metrics
  • Data Set B: Customer Satisfaction

Note: Ensure that axes are properly labeled and scales are consistent for accurate interpretation of the data.

In conclusion,

Selecting the right chart type when you have two unrelated data types is essential for effective data visualization. Consider the nature of your data and what insights you want to convey before making your choice. Whether it’s a bar chart, scatter plot, pie chart with subcategories, line chart, or radar chart, each chart type offers unique advantages for presenting your data in a visually engaging and informative way.
