Units on every metric
What's new
Newhedge now declares the unit for most metrics in the API catalog and in the definition record.
units_source says where each unit came from: declared when Newhedge states the unit, chart when it is the unit the metric's own chart already shows beside the value, and heuristic when it was inferred from the metric name. A metric whose unit is not established publishes units: null rather than a guess.
Methodology
Ratio metrics such as the AVIV ratio, the put/call ratio, and SOPR are no longer labelled as percentages.
The vague count and rate labels are gone. Those metrics now name what they count, such as blocks, transactions, or addresses.
