What is a stacked area chart?
A stacked area chart piles several series on top of each other, so the top edge traces the total while the bands inside show each part’s contribution. It answers two questions in one picture: how big is the whole, and what is it made of. Product and marketing teams reach for it to show traffic by channel, revenue by plan, or usage by platform over time.
How to make a stacked area chart
Import your CSV
One row per time period, a date column, and one numeric column per part of the whole. Drag it in or paste from a spreadsheet.
Select the parts
Check the series that make up your total, up to five. Each becomes one colored band of the stack.
Pick absolute or relative
Keep the default to show real totals, or turn on % Relative in Advanced to rescale every period to 100% and expose mix shifts.
Download or embed
Export as PNG or JPG for decks, or copy the HTML embed for pages you control.
When to use a stacked area chart
Composition over time: traffic by channel, revenue by plan, users by platform
Showing the total and the mix in one chart
The % Relative view, which turns the stack into shares of 100%
When not to: If your series don’t add up to a meaningful whole — say, temperature and revenue — stacking them is misleading. Plot them as separate lines instead.
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.

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.
Bar chart
Compares amounts across categories. The right pick when your x-axis is a set of things, not a timeline.
Stacked bar chart
Category totals plus what each one is made of, in a single chart.
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.
