Sometimes however the default representations of some items are too limited, so BE allows you to override the default displays with your own customisations.
Modifications are made through:
Main Menu > Database Management > Database - Question Management > Question - Edit > Select the campaign > Select the question whos visualisation you want to change > Down in the "Grouping Options" section is "Visualisation Option"
The customisations are entered in a single line of data separated by commas.
