How to How to Create Multi-Axis Chart in Excel in Excel - Practical Guide

In this tutorial, you'll learn how to create multi-axis charts in Excel to visualize datasets with different scales and units on a single chart. This technique is essential when comparing metrics like revenue (in dollars) and unit count simultaneously, making data relationships immediately clear without distorting the visual representation.

Why This Matters

Multi-axis charts are crucial for professional reporting when comparing metrics with different units or scales; they enable accurate data storytelling without misleading visualizations.

Prerequisites

•Basic understanding of Excel chart creation
•Data organized in columns with clear headers
•Knowledge of selecting data ranges
•Familiarity with the Insert menu

Step-by-Step Instructions

Prepare Your Data

Organize your data in columns with headers, ensuring one column contains the category labels and additional columns contain the metrics you want to compare on different axes.

Select All Data

Select the entire data range including headers: click the first cell, then drag to the last cell containing data, or use Ctrl+Shift+End to select to the last used cell.

Insert a Chart

Go to Insert > Charts > Recommended Charts, choose a column or line chart, and click OK to insert the initial chart into your worksheet.

Change Series Axis Assignment

Right-click the data series you want on a secondary axis, select Format Data Series, then go to Series Options and choose Secondary Axis to assign it a separate scale.

Customize and Format

Adjust axis titles, legends, and colors via Chart Design > Chart Elements; add axis titles for clarity and modify colors to distinguish between primary and secondary axis series.

Alternative Methods

Using Combo Charts Directly

Select your data and go to Insert > Charts > Combo Chart, then assign different chart types to each data series with secondary axis option enabled for immediate multi-axis setup.

Manual Axis Editing

Create a basic chart, then manually adjust each series by double-clicking the chart, right-clicking each series individually, and assigning primary or secondary axis without using the wizard.

Tips & Tricks

✓Use contrasting colors for primary and secondary axis series to make the distinction immediately obvious to viewers.
✓Add descriptive titles to both axes (e.g., 'Revenue ($)' and 'Units Sold') to clarify the scale for each metric.
✓Avoid using multi-axis charts when data scales are similar; a single-axis chart is clearer in those cases.
✓Consider using line charts for one series and columns for another to visually differentiate the axes.

Pro Tips

★Use secondary axis for data with significantly different magnitudes (e.g., revenue in thousands vs. quantity in hundreds) to prevent one series from appearing flat.
★Combine column charts with line charts on multi-axis displays for superior visual clarity and professional appearance.
★Always include a legend explaining which series corresponds to which axis to prevent viewer confusion.

Troubleshooting

Secondary axis series appears flat or invisible

The scale difference is too extreme; right-click the secondary axis, select Format Axis, and manually adjust the Maximum and Minimum values to a more appropriate range.

Both axes show the same scale despite assigning secondary axis

Ensure the secondary axis assignment was successful by clicking the chart, then going to Chart Design > Select Data and verifying the secondary axis is listed.

Legend shows both series but they're hard to distinguish

Click the chart, go to Chart Design > Chart Elements > Legend > Right, then manually format each series with distinct colors via Format Data Series.

Frequently Asked Questions

Can I create a multi-axis chart with more than 2 axes?

Excel natively supports only 2 axes (primary and secondary), but you can create the illusion of multiple axes by using combo charts with different chart types for visual distinction.

What's the best chart type combination for multi-axis?

Column charts paired with line charts work best because the visual distinction makes it immediately clear which series uses which axis without requiring legend inspection.

Should I use multi-axis charts when comparing percentages?

No; if both metrics are percentages, use a single axis as they share the same scale (0-100%), and multi-axis only adds unnecessary complexity.
