Frequently Asked Questions
What is a combo chart?
A combo (combination) chart overlays two different chart types — typically bars and a line — on the same axes. This lets you compare two related metrics with different scales in one visual.
When should I use a combo chart?
Use combo charts when you have two related metrics with different units or scales — like revenue (dollars) and growth rate (percentage), or sales volume and average price.
Does it support dual Y-axes?
Yes — the bars use the left Y-axis and the line uses the right Y-axis, allowing different scales.
Can I add more than one line?
The quick tool supports one bar series and one line series. For multiple overlays, use the full /editor.
