As clever man said, better to do later, then never.
So, about Personality test. To enable that you should do following:
- Set "Display charts for "Personality Test" feedback" to "Yes" in Questionnare settings (Site administration-->Plugins-->Activity modules-->Questionnaire)
- After that create new Questionnaire and when adding questions set the "Responce is required" to "Yes", because this data will be used in charts.
- When all questions are entered, go to Yours Questionnaire "Advanced settings" and look there for "Feedback options". There You can set up a chart and various ways how to show results.
- Pay attention that if you use 1 feedback, then there will be only charts with single column available. If use 2 or more, then another charts will be available to use.
