Line Chart With Secondary Axis

Wednesday, December 20th 2023. | Chart Templates

Line charts are a popular way to visualize data trends over time. They provide a clear and concise representation of how a variable changes over a specific period. However, sometimes it becomes necessary to compare two variables that have different scales or units. This is where a line chart with a secondary axis comes into play.

What is a Line Chart with Secondary Axis?

A line chart with a secondary axis is a variation of the traditional line chart that allows for the simultaneous comparison of two variables that have different scales. In this type of chart, two lines are plotted on separate vertical axes, each representing a different variable. This allows for a more accurate comparison between the two variables, as the scales can be adjusted to best fit the data being displayed.

Why Use a Line Chart with Secondary Axis?

There are several reasons why you might choose to use a line chart with a secondary axis:

1. Comparing Variables: If you have two variables that have different scales or units, using a line chart with a secondary axis allows for a more accurate comparison between the two variables. This can help identify any correlations or patterns that may exist between the variables.

2. Highlighting Trends: By plotting two variables on separate axes, you can easily see how they change over time. This can help identify any trends or patterns that may be occurring in the data.

3. Improving Understanding: A line chart with a secondary axis can help improve the understanding of complex data sets. By visualizing two variables together, it becomes easier to see the relationship between the two and draw conclusions from the data.

Sample Line Charts with Secondary Axis

Here are five examples of line charts with secondary axes:

This chart shows the sales of a product over time on the primary axis, and the corresponding advertising spend on the secondary axis. This allows for a comparison between the two variables and helps determine the effectiveness of the advertising campaigns.

2. Temperature vs. Precipitation

This chart compares the temperature and precipitation levels over time. The primary axis represents temperature, while the secondary axis represents precipitation. This allows for a clear understanding of how these two variables interact and influence each other.

3. Website Traffic vs. Conversion Rate

This chart displays the website traffic and conversion rate over a specific period. The primary axis represents website traffic, while the secondary axis represents the conversion rate. By plotting these two variables together, it becomes easier to identify any trends or patterns that may exist.

4. Stock Price vs. Volume

This chart shows the stock price and trading volume of a particular stock over time. The primary axis represents the stock price, while the secondary axis represents the trading volume. This allows for a comparison between the two variables and helps identify any correlations or patterns.

5. Revenue vs. Expenses

This chart compares the revenue and expenses of a company over a specific period. The primary axis represents revenue, while the secondary axis represents expenses. By visualizing these two variables together, it becomes easier to understand the financial performance of the company.

Conclusion

A line chart with a secondary axis is a powerful tool for comparing two variables with different scales or units. It allows for a more accurate and meaningful analysis of the data, helping to identify correlations, trends, and patterns. By visualizing the data in this way, it becomes easier to draw insights and make informed decisions. Whether you are analyzing sales data, financial performance, or any other type of time-series data, a line chart with a secondary axis can provide valuable insights.
