designed Experiment Box Plot
Appends a MultiBoxPlot comparing per-replication distributions across executed design points for a single responseName in de.
Each box represents one executed design point, labelled "Point N" in execution order, sourced from DesignedExperimentIfc.observationsAsMap. Design points for which responseName produced no observations are omitted. Nothing is emitted when no design points have been executed.
Axis labels default to "Design Point" (x) and responseName (y); override either via xAxisLabel / yAxisLabel.
Parameters
the designed experiment
the response to visualise; should appear in DesignedExperimentIfc.responseNames
optional plot caption; defaults to "Distributions by Design Point — <responseName>"
optional override for the x-axis label
optional override for the y-axis label
