it is not possible at the moment to create a spiderweb diagramme with certain criteria from a questionnaire. It would be great if that could work, particularly for evaluations. We can export data to Excel for that but that is of course not so great.
Linking your original post here for reference:
I think this would have to be done in an external tool. If you have a tool in mind already and are having trouble getting data from KoBoToolbox into that tool, we might be able to think of a way to help with that.
