Does anyone know if it is possible when modifying a bunch of mosaic plots to "broadcast" and/or change the default colors and to have them all display percentages on the plots? I've tried holding down the Ctrl key while doing this but it doesn't apply the changes to all mosaic plots. I have been able to find anything in Preferences.
You can change the default categorical color theme in preferences (JMP 8 or later), or you can give the coloring column a Value Colors property. Either of these will take effect when you redo the analysis.
