Hi @MKostura ,
From what I can see, there is no way to add the legends for those 'Cell Box Plots' - I would suggest adding this to the Wish List so that the developers can be aware.
As a workaround - I've wrote you a JSL script that will pop those columns up as a legend plot (albeit in a separate window). Just adapt the column names to suit the names you're using in your heirachichal clustering.
dt=current data table();
cp=Cell Plot(
Scale Uniformly( 0 ),
Center at zero( 0 ),
Y(:Type1, :Type 2)); //Write in the name of your columns in here!
cp<<legend(1);
//hide the outline box and the titles to make the appearance cleaner
report(cp)[LineupBox(1)]<<Visibility("Collapse");
report(cp)[OutlineBox(1)]<<set title("");
