How to build a Google Slides stacked bar chart with ChartKit

Stacked bars are useful when you need to show both total size and composition at the same time. When the composition is the only point, switch to a 100% bar so the audience compares mix rather than absolute scale.

ChartKit data editing view used to build stacked bar charts in Google Slides. — Stacked bars work best when segment order, totals, and labels are all tuned for the question the audience needs answered.

Choose the right variant

Use a stacked bar when

You need to compare both the total and the contribution of each segment across categories.

Use a 100% bar when

You want the audience to compare mix, share, or allocation while removing differences in total size.

Build steps

Start with categories that answer a single clean comparison question.
Keep segment order consistent across every bar so the eye does not have to relearn the encoding.
Use labels selectively on the segments or totals that matter most to the story.
Adjust spacing and colors so the chart reads clearly on a slide, not just in a spreadsheet cell.

Checklist

Consistent segment order

Keep segment order identical from bar to bar so the audience can compare patterns quickly without relearning the encoding.

Totals when scale matters

If total size is part of the story, show totals or labels that make the whole stack easy to compare.

100% bars when mix matters

Normalize the bars when composition is the story so the audience compares shares instead of being distracted by differences in scale.

Presentation advice

If one segment is the real punchline, call it out. If the story is about the whole stack, show totals. If the story is about mix, remove any visual noise that competes with the shares.

FAQ

Common stacked-bar questions.

How do I choose between a stacked bar and a 100% bar?

Use a stacked bar when both total size and segment contribution matter. Use a 100% bar when the point is mix, share, or allocation across categories.

What usually makes stacked bars hard to read on slides?

Inconsistent segment order, too many small slices, and labels on every segment are the most common problems. Reduce noise and emphasize the elements that support the takeaway.

What should I compare this with?

Compare this guide with the waterfall guide if your story is about change between totals rather than composition within totals.
