Beyond Basic Graphing: Exploring Secondary Axis Functionality in Excel

Charts and graphs are powerful tools for visualizing data in Excel. They help us understand complex information and identify patterns and trends. However, when you have two sets of data with different scales, it can be challenging to effectively represent them on a single chart. That’s where a secondary axis comes in.

In this article, we will explore two easy ways for how to add secondary axis in Excel. Whether you’re using MS Excel on a Mac, PC, or Google Docs, we’ve got you covered. By the end of this guide, you’ll be able to create charts with multiple sets of data and different scales, providing a clear and comprehensive view of your information.

Understanding the Need for a Secondary Axis

Before we dive into the mechanics of adding a second axis, let’s understand why it’s necessary in the first place. Imagine you have a dataset that includes sales and profit margin for a company over several years. If you plot both sets of data on the same axis, it becomes challenging to compare the two.

For example, let’s say you want to analyze the change in profit margin from one year to another. With only a primary axis, and without the second axis, it’s difficult to visually interpret this information. By adding a secondary axis, you can plot profit margin on a separate scale, making it easier to compare and analyze the data effectively.

Method 1: Adding a Secondary Axis with Recommended Charts

The first method we’ll explore is adding a secondary axis using the recommended charts feature in Ms Excel. This method is straightforward and can save you time when creating your chart.

1. Select the data you want to include in the chart.
2. Navigate to the “Insert” tab in Excel.
3. Click on the “Recommended Charts” button.
4. Choose the chart type that includes a secondary axis in the preview window.
5. Click “OK” to create the chart with the secondary axis automatically added.

By following these steps, you can quickly generate a chart with a secondary axis, allowing you to compare two sets of data with different scales effortlessly.

Method 2: Adding a Secondary Axis Manually

If the recommended Excel chart doesn’t include a secondary axis option or if you prefer more control over the axis customization, you can add a secondary axis manually. Here is a simple Excel tip. This method gives you the flexibility to create the exact chart you need.

1. Start by inserting the basic chart from the recommended charts, even if it doesn’t include a secondary axis.
2. Double-click on the small bars at the bottom of the chart to open the Format Data Point options.
3. In the Series Options, check the “Secondary Axis” option to add a secondary axis to the chart.
4. The chart will now appear stacked, with the primary y-axis representing one set of data and the secondary y-axis representing the other.
5. If you want to change the chart type, select the chart and go to the “Insert” tab. Choose “Combo Charts” from the “Change Chart Type” dialog box.
6. In the Combo Charts window, select the desired chart type for each axis. You can customize the chart to best represent your data.
7. Click “OK” to apply the changes and create the chart with the secondary axis.

By manually adding a secondary axis, you have full control over the appearance and customization of your chart, allowing you to present your select data precisely the way you want.

Tips for Using a Secondary Axis Effectively

Now that you know how to add secondary axis in Excel, it’s important to understand some best practices for using it effectively. Here are a few tips to keep in mind:

1. Use a secondary axis when you have two sets of data with different scales or units of measurement. It helps maintain clarity and allows for accurate comparison.
2. Label each axis clearly to avoid confusion and ensure that viewers understand which data is represented on each axis.
3. Choose appropriate chart type for each data set. For example, use a bar chart for sales and a line chart for profit margin to clearly differentiate between the two.
4. Avoid overcrowding the chart with too many data series. If you have more than two sets of data, consider using a different visualization technique or breaking the data into multiple charts.
5. Regularly update the data in the chart to reflect the most recent information. This will ensure that your analysis and insights are based on accurate and up-to-date data.

By following these tips, you can make the most of a secondary axis and create charts that effectively communicate your data.
