Adding a secondary axis in Google Sheets can be a game-changer when it comes to presenting data that has different scales or units. Itโs a straightforward process that involves creating a combo chart and then customizing it to fit your needs. By the end of this short intro, youโll have a basic understanding of adding a secondary axis to your charts in Google Sheets.
Step by Step Tutorial on How to Add Secondary Axis Google Sheets
Before we dive into the nitty-gritty, letโs clarify what weโre aiming for here. Adding a secondary axis allows you to plot data on two different scales on the same chart. This can be particularly useful when you have a set of data with large values and another with much smaller values. By following the steps below, youโll be able to present your data more clearly and effectively.
Step 1: Select your data
First things first, highlight the data you want to include in your chart.
When selecting your data, make sure you include the headers. This will make it easier to differentiate between the various data sets once theyโre plotted in the chart.
Step 2: Insert a chart
Click on โInsertโ in the top menu, then select โChartโ from the dropdown.
Google Sheets will automatically insert a chart based on the data youโve selected. Donโt worry if it doesnโt look right just yet; weโre going to tweak it in the following steps.
Step 3: Choose a combo chart
In the Chart editor, which appears on the right side of the screen, go to the โChart typeโ dropdown and select โCombo chartโ.
The combo chart is the key to adding a secondary axis as it allows for different data to be plotted using different chart types within the same overall chart.
Step 4: Customize the series
Still in the Chart editor, scroll down to the โSeriesโ section. Here you can assign each data set to either the primary or secondary axis.
Youโll need to click on each series individually and select which axis to use from the dropdown menu in the Series options. Typically, youโll put the data with larger values on the primary axis and the data with smaller values on the secondary axis.
Step 5: Adjust the secondary axis
After assigning your data to the appropriate axes, you can adjust the scale of the secondary axis to better fit your data.
You can tweak the scale of the secondary axis by clicking on it and adjusting the options in the โAxisโ section of the Chart editor. Be sure to make the scale of the secondary axis relevant to the data being plotted against it.
Once youโve completed the above steps, your chart should now include a secondary axis. This allows for a more accurate and visually appealing representation of datasets with different scales or units.
Tips for Adding Secondary Axis Google Sheets
- Always check that your data is accurate and correctly formatted before adding it to a chart.
- Use contrasting colors for the series on the primary and secondary axes to make the chart easier to read.
- Consider using different chart types for the primary and secondary data series for added clarity.
- Donโt forget to add labels to your axes to help viewers understand what theyโre looking at.
- Play around with the customization options in the Chart editor to create a chart thatโs both informative and visually appealing.
Frequently Asked Questions
How do I select the correct chart type for my data?
Experiment with different chart types to see which one best represents your data. Combo charts are generally the best option when using a secondary axis.

No, secondary axes are only available in combo charts and certain other chart types that support multiple data series plotted against different scales.
Summary
