In Excel, adding a second Y-axis to a chart can help you compare two different data sets with different scales more clearly. Simply, you start by inserting your data into a chart, then add the secondary Y-axis through the chart tools. This is a quick way to improve the readability of your data visualizations.
How to Add Second Y Axis in Excel
When you follow these steps, you’ll be able to add a second Y-axis to your Excel chart, making it easier to compare two sets of data that have different value ranges.
Step 1: Select Your Data
Highlight the data you want to chart, including both sets of data.
This is the first step because selecting your data ensures that both sets of information are included in the chart. If you miss this step, your chart won’t display all the information you need.
Step 2: Insert a Chart
Go to the ‘Insert’ tab and choose a chart type (like Line or Column Chart).
Here, you’re actually creating the chart. Make sure you pick a chart type that best represents your data. Line charts are often a good choice for time series data.
Step 3: Select the Data Series to Add to Secondary Axis
Click on one of the data series in the chart to select it.
Selecting the data series you want to plot on the second Y-axis tells Excel which data set needs a different scale.
Step 4: Format Data Series
Right-click the selected data series and choose ‘Format Data Series.’
This opens up a menu where you can adjust various settings for the data series.
Step 5: Add Secondary Axis
In the ‘Format Data Series’ pane, select ‘Secondary Axis.’
Choosing ‘Secondary Axis’ adds a second Y-axis to your chart, allowing you to differentiate between the two data sets easily.
Step 6: Fine-Tune Your Chart
Adjust the chart elements as needed for better readability.
You can modify things like axis titles, data labels, and chart styles to make your chart easier to understand.
After completing these steps, you’ll see a second Y-axis on your chart. This will allow you to compare two sets of data that have different scales more effectively.
Tips for Adding Second Y Axis in Excel

- Double-Check Your Data: Ensure that both sets of data are correctly selected and represented in the chart.
- Customize for Clarity: Adjust elements like gridlines, data labels, and chart titles to enhance readability.
