Example
In this example, we select 3 factors: "Engine Information.Driveline", "Identification.Classification" and "Identification.Year"(marked with a red box) . Select them as Factor in the plot_multivari dialog.
Unstack source data column with factor 1 and factor 2, including the column factor 3(marked with a pink box) ; with 8 unstacked columns, plot box plots only with connected mean points(Yellow-Filled scatter + black line). In the Plot Details dialog, set factor 2 as Subgrouping in Group tab and factor 3 as Horizontal Panel Column in Panel tab.
Calculate the mean values for subgroups(marked with a blue box) and different panels(marked with a green box) , plot them as line+scatter plots to present these mean values.
