A chart is complete when its evidence is complete.
These fields are required in product, Admin exports, and external marketing communication.
01
Axis
Show baseline, tick values, unit, and measurement domain. Never crop a curve into a false move.
02
Time
Use 24-hour time plus IANA zone or UTC. Relative labels such as “now” are secondary.
03
Precision
Probability 0.1%; decimal odds 2 dp; currency compacted only after the exact value is available.
04
Events
Label the event and timestamp. Keep the evidence line visible across the annotation.
05
Status
Separate observed, estimated, delayed, and suspended data with text—not color alone. Reserve Aqua for verified live or realtime state.
06
Source
Name the market, provider or internal dataset, sampling interval, and last update.
