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. [See plans](/pricing) ## Frequently asked questions ### What data shape does a stacked bar chart need? One row per category or period, one numeric column per segment. Each column becomes one layer of the stack, in its own color. ### Can I make a 100% stacked bar chart? Yes. Turn on % Relative in the Advanced section and every bar stretches to 100%, showing each segment as a share of the total. ### How many segments can I stack? Up to five, matching the tool’s five-series limit. More than that stops being readable in any stacked chart. ### Stacked bars or grouped bars — which should I use? 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. ### Can I stack bars over time? 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. ### Is there a limit on how many charts I can make? 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. ## Why use this chart maker ### Create beautiful charts instantly Every chart is drawn in Amplitude’s own palette and typography, the same ones behind our product.
