FAQ
Frequently Asked Questions
What is a dual axis chart maker?
A dual axis chart maker is a tool that lets you plot two data series with different scales on the same chart using a left Y-axis and a right Y-axis. MakeCharts combines this with combo chart support so you can mix bars, lines, and areas freely.
What is a combo chart?
A combo chart (combination chart) blends two or more chart types — most commonly bars and lines — in a single visualization. It is especially useful when you need to compare a volume metric (bars) against a rate or percentage metric (line) side by side.
When should I use a dual axis combo chart?
Use a dual axis combo chart when your two metrics have very different units or scales and would be unreadable on a single axis. Classic examples include revenue (dollars) vs. growth rate (percent), or order volume vs. average fulfillment days.
Can I make a dual axis chart for free?
Yes. The full dual axis combo chart maker is free with no sign-up required. You can create, customize, and download your chart at no cost. AI-powered generation is also available on the free plan with included credits.
How do I add a second Y-axis to my combo chart?
In the Series Settings panel, each series has a Y-Axis column where you can choose 'Left' or 'Right'. Toggle 'Show Right Y-Axis' in the Axis Settings and give it a label. The chart updates instantly.
Can I mix bar and line series in the same chart?
Yes. Every series has a Type selector that lets you switch between Bar, Line, and Area independently. You can have two bar series on the left axis and one line series on the right axis, or any other combination that fits your data.
How do I create a dual axis chart with AI?
Type a description in the prompt field — for example, 'Monthly sales as bars and profit margin as a line, January to December.' The AI will generate the chart data, series types, and axis assignments automatically. You can then edit any detail.
What file formats can I download?
You can download your dual axis combo chart as a PNG for presentations and documents, or as an SVG for scalable, print-quality output. SVG export is available on Starter and above.
Can I embed the combo chart on my website?
Yes. Plus and Pro plans include embed codes. Copy the snippet and paste it into any website, blog, or CMS — the chart renders live and responsively for your visitors.
Is MakeCharts suitable for professional reports?
Absolutely. MakeCharts outputs high-resolution images with clean typography, grid lines, and legend options that meet the standards of business reports, investor decks, and academic papers. The dual axis combo chart is one of the most-used styles for executive dashboards.
