HORIZON

folded value bands per row: darker = higher, in tight strips. Needs: 6-12 series over many periods, scanned for anomalies, not read.

trendpattern

DL-01 AGRAW

Use when

WARN: dense monitoring walls scanned for where and when, never how much
many series in little vertical space

Do not use when

reading values (folding destroys them by design)
audiences who have never seen a horizon chart

See instead

under ~6 series: CH-TIM-06
values must be read: CH-TIM-01

Alternatives

CH-TIM-06 (fewer rows, simpler)
CH-TIM-01 (few series, exact)

Rules

3 folded layers, shared across rows; opacity encodes the layer
the layer key (each layer = N units) printed under the strips
rows share one scale: darkness IS comparable across rows

Never do this

WARN ENTRY: horizons are for trained monitoring eyes; anyone else needs CH-TIM-06
per-row scales sold as comparable
reading values off folds

QA before delivering

shared scale
layer key printed
>= 8 points per row
source present

Data shape

title	action title naming the anomaly
source	bottom-left always
unit	of the folded layers
rows	[{label, values}], >= 8 points
