BarRenderer<D> class

Renders series data as a series of bars.

Inheritance

Constructors

BarRenderer({BarRendererConfig<D>? config, String? rendererId})
factory
BarRenderer.internal({required BarRendererConfig<Object?> config, required String rendererId})
This constructor is protected because it is used by child classes, which cannot call the factory in their own constructors.
