Two figures use different units and one axis is logarithmic. How should a comparison be documented?
Record format: question; proposed response; source or method; limitation. Use a dated correction only if the underlying wording or evidence changes. Record RESEARCH-30824.
Record the original units and axis transformation, show any conversion explicitly and retain the original values. Do not compare apparent visual distances across incompatible scales.
Clarification for “Units and scale: prevent a silent comparison error”: the point beginning “Record the original units and axis transformation, show any conversion…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
