Chartjs.Halogen

component :: forall m. MonadAff m => Component Query ComponentInput Output m

Halogen component that renders and manages a Chart.js chart.

Input: ComponentInput from Chartjs.Callbacks (config + callbacks + updateMode). Use simpleInput for the common case (no callbacks, animation suppressed on updates).

Queries: All Chart.js instance methods are available via the Query type. Use H.request for methods that return values, H.tell for side-effect-only methods.

Output: ChartReady inst when the chart is created (for consumers who need the raw instance), ChartError msg on create/update/query failures.

data Query a

Queries for interacting with the chart instance. Use H.request for queries that return a value, H.tell for fire-and-forget.
