What is a stacked bar chart?

A stacked bar chart divides each bar into segments, one per sub-category, so the full bar shows the total and the segments show its composition. It compresses two charts into one: the comparison across categories and the breakdown within each. The 100% variant rescales every bar to equal height, trading away totals to make shares directly comparable.

How to make a stacked bar chart

  1. Import your CSV

    One row per category or period, one numeric column per segment. Drag the file in or paste from a spreadsheet.

  2. Pick the segments

    Check up to five columns — each becomes one layer of the stack, in a fixed brand color.

  3. Absolute or 100%

    Keep real totals, or flip on % Relative in Advanced to stretch every bar to 100% and compare shares.

  4. Download or embed

    Export as PNG or JPG, download the data as CSV, or copy the static HTML embed.

When to use a stacked bar chart

  • Totals plus composition: revenue by region split by product line

  • Comparing a mix across categories or time periods

  • The % Relative view for share-of-total comparisons

When not to: Middle segments are hard to compare precisely because they don’t share a baseline. If exact segment comparison matters more than the total, use grouped bars or separate charts.

Charts that update themselves

A chart from a CSV is a snapshot. Amplitude charts read straight from your product’s data — funnels, retention, and trends that stay current without another export. Plans start free.

Frequently asked questions

One row per category or period, one numeric column per segment. Each column becomes one layer of the stack, in its own color.
Yes. Turn on % Relative in the Advanced section and every bar stretches to 100%, showing each segment as a share of the total.
Up to five, matching the tool’s five-series limit. More than that stops being readable in any stacked chart.
Stacked when the total matters and segments just explain it; grouped when you need to compare segments precisely, since every grouped bar starts from zero.
Yes — use a date column as the x-axis and each period gets its own stacked bar. For many periods, the stacked area chart tells the same story with less ink.
There is no cap and no metering. Build and export as many stacked bar charts as you like; because nothing is stored server-side, there is no quota to track.

Make another kind of chart

Your data carries over, so switching type costs you nothing — no re-importing. Every chart below is drawn by the same tool, in Amplitude’s palette.

  • Line chart

    The default for trends over time. Use it for metrics like weekly active users, revenue, or signups by month.

  • Area chart

    A line chart with the space under it filled in. Good when the volume itself matters, not just the direction.

  • Stacked area chart

    Shows how parts add up to a whole over time, like traffic by channel or revenue by plan.

  • Bar chart

    Compares amounts across categories. The right pick when your x-axis is a set of things, not a timeline.

  • Horizontal bar chart

    A bar chart turned sideways. Use it for rankings or when category names are too long to fit under columns.

  • Pie chart

    Share of a total at a single point in time. Works best with five or fewer slices, so this pie chart generator groups the rest into “Other” for you.

  • Donut chart

    A pie chart with an open center. Same job as a pie, with a lighter look.

  • Funnel chart

    Drop-off across sequential steps, like visit, signup, activation, purchase. The classic product analytics view.

  • KPI chart

    Turns each series into a headline number with its total and average, for when the figure matters more than the trend.
