CngxThreshold

Threshold reference atom. Renders a single horizontal <line> at yScale(value) spanning the chart's full width, plus an optional <text> label at the right edge.

Common use: target threshold ("budget cap"), warning bands, or any "line at value" reference. Always reads scales from CNGX_CHART_CONTEXT.

Attribute-selector on <svg:g> - see CngxLine for why.
