import { CngxChartContext } from '@cngx/common/chart'

Description#

Reactive context published by <cngx-chart> to its content children. Layer atoms ([cngxLine], [cngxBar], ...) and [cngxAxis] inject CNGX_CHART_CONTEXT to read the parent chart's scales, dimensions, data length, and data array without needing a direct reference to the parent class. Token is non-generic at the DI boundary; layer atoms call data<T>() to narrow the array to their own <T> - the single boundary cast lives inside CngxChart's data<U>() method, not at every consumer site.

Methods#

data#T[]

Generic-aware data accessor. Reads the chart's reactive data array; the consumer's <T> parameter narrows the returned type without a per-call cast at the consumer site. The chart performs one boundary cast in its implementation.
