If you want to present two sets of data on the same chart in Excel, adding a second vertical axis can be a game changer. By doing this, you can easily compare different data series with varying scales. Here’s a quick guide to adding that second vertical axis to your Excel chart.
How to Add Second Vertical Axis in Excel
Adding a second vertical axis in Excel allows you to plot two sets of data with different value ranges on the same chart. This is especially useful when you have one data series with values much larger or smaller than the other. Below are the steps to achieve this.
Step 1: Open Your Excel File
Open your Excel file and select the chart you want to modify.
Make sure that the data you want to compare is already plotted on a chart. If it’s not, go ahead and create a chart by selecting your data and choosing a chart type.
Step 2: Select the Data Series
Click on the data series that you want to plot on the second vertical axis.
It’s important you ensure you click specifically on the data series. You can usually see small circles or squares appear on the data points when selected correctly.
Step 3: Format Data Series
Right-click on the selected data series and choose "Format Data Series."
A menu will pop up. Selecting "Format Data Series" will open a new sidebar or dialog box depending on your Excel version.
Step 4: Choose Secondary Axis
In the "Format Data Series" pane, check the box for "Secondary Axis."
Doing this will immediately shift your selected data series to the second axis, creating a more readable and balanced chart.
Step 5: Adjust Axis Options
Adjust the axis options as needed to make sure both data series are clearly visible.
You might want to tweak the axis titles, ranges, or units to better present your data. This makes your chart more informative and easier to understand.
After completing these steps, your chart will now display two vertical axes, allowing you to compare different data series more effectively.
Tips for Adding Second Vertical Axis in Excel
- Data Selection: Ensure your data series are correctly selected to avoid confusion.
- Chart Type: Use a line or bar chart for better clarity when adding a second axis.
- Axis Labels: Clearly label both primary and secondary axes to avoid misunderstandings.
- Color Coding: Use different colors for each data series to make them easily distinguishable.
- Axis Range: Adjust the range of both axes to fit the data well and provide a balanced view.
