render Ci Plot
Render a side-by-side CI plot for responseName — one mean ± CI bar per checked experiment that records the response.
Parameters
confidence level for the CIs (default 0.95). Each alternative's CI is computed from its own observations via Statistic.confidenceIntervals, so unequal replication counts are allowed (unlike MCA).
optional vertical reference line on the value axis (e.g. a target throughput or known theoretical mean). null (the default) suppresses it.
optional plot caption. Blank / null falls back to "Mean ± <CL>% CI — <response>".
optional report title. Blank / null falls back to "Comparison — Confidence Intervals — <response>".
optional override for the x-axis label (the value axis). Defaults to responseName.
optional override for the y-axis label (the alternative axis). Defaults to "Experiment".
