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. Use Dual axis when bars and line values have different units or scales. You can also switch to Shared scale or Indexed trend when those views make the comparison clearer.

Can I customize labels and values?

Yes. The combo chart studio includes editable chart title, subtitle, axis labels, metric names, value prefixes, value suffixes, colors, and category values.
