Charts bring your data to life, but what happens when you need to compare metrics with completely different scales? That's where a secondary axis saves the day. Let me show you how to master this game-changing feature in Google Sheets - and how Excelmatic makes it effortless with AI.
Why You Need a Secondary Axis (And When to Use One)
Picture this: you're analyzing quarterly performance with revenue in dollars and units sold in quantities. Plotting both on the same axis makes one metric look tiny. A secondary axis gives each dataset its own scale, making comparisons crystal clear.
But here's the pro tip: don't overdo it. Stick to 2-3 data series max to keep your charts readable. And if your metrics have completely unrelated units (like temperature and sales), consider separate charts instead.
The Manual Way: Adding a Secondary Axis in Google Sheets
Step 1: Prep Your Data
Organize your data in clean columns with clear headers. No blank cells allowed - they'll mess with your chart later. Pro tip: Format numbers consistently (all dollars as currency, etc.).
Step 2: Create Your Base Chart
- Highlight your data range
- Click Insert > Chart
- Choose column or line chart (these work best for secondary axes)
Step 3: Add That Secondary Axis
- Click your chart to open the Chart Editor
- Go to Customize > Series
- Select your second metric (like "Units Sold")
- Check "Axis" and choose "Right axis"
Voila! Your chart now shows both metrics clearly on separate scales.

Pro Tips for Killer Charts

When to Break Up With Your Secondary Axis
Sometimes less is more. Avoid secondary axes when:
- Your data is too complex (try separate charts)
- The metrics are completely unrelated
- You're working with very small datasets
