Chart examples

Real renders of the stacked series chart — each one is the same component with different property values, and the API payload below each preview reproduces it exactly.

Revenue split by product line

Subscriptions vs one-time sales stacked per month, brand-colored.

API overrides for this example

{
  "sales.chartType": "bar",
  "sales.data": [],
  "sales.series": [
    {
      "name": "Subscriptions",
      "data": [
        24,
        28,
        31,
        36,

Support tickets by priority

Low / high priority ticket volume stacked per week for an ops report.

When to use the stacked series style

Revenue split by product line per month
Team workload composition reports
Year-over-year comparisons in one bar

Use it dynamically via the API

Feed fresh numbers via '<key>.data' (or '<key>.series' for multi-series), and swap '<key>.labels' or '<key>.chartType' per render.
