Pyramid Chart
A pyramid stacks the parts of a whole from the largest at the base to the smallest at the top. Each level’s area matches its share; switch to height to compare.
About this chart
Area or height?
A pyramid narrows towards the top, so a level sized by its height looks smaller than its value. Sized by area, the default, each level takes the share of the pyramid it stands for. Use a pyramid when the parts have an order, from a broad base to a small top.
Good for
- Levels with a natural order, base to top
- Customer tiers, team levels or price plans
- Showing how much the base outweighs the top
Think twice when
- Parts with no order: a pie or bar chart fits better
- Exact comparisons: sloped sides make levels hard to measure
- A base that isn’t the biggest part: the shape will mislead
For developers
Get the code.
Built with amCharts 5, a JavaScript library. The JavaScript includes your theme and renderer (canvas or SVG); the JSON also follows the changes you make with the controls.
For projects that use npm:
How it reads:
npm install @amcharts/amcharts5. See Getting started.
The same chart as a JSON config. Chart Maker reads and writes this format, the library's JSON parser turns it into a chart, and the <am5-chart> element puts it on a page with no code.How it reads:
"type" is the class to create and "settings" what you would pass to its new() in code; "properties" fill in its parts, lists such as series and axes or templates such as columns.template; "refs" holds objects used in more than one place ("#series-0" stands for the one named series-0); a string starting with "@" takes a value from another object, such as "@series.get('fill')".
A complete page. Save it as an .html file and open it in a browser.
