}Usage
pointAndFigure() from @reincharts/indicators builds columns of X (rising) and O (falling) boxes. A new column starts
when the price reverses by reversal boxes (3 by default).
import { PointAndFigureSeries } from "@reincharts/series";
import { pointAndFigure } from "@reincharts/indicators";
const columns = useMemo(() => pointAndFigure(bars, { boxSize: 0.5, reversal: 3 }), [bars]);
<ChartCanvas data={columns}>
<PointAndFigureSeries />
</ChartCanvas>;
