I'm using ke_questionnaire 3.1.7, TYPO3 CMS 7.6 with PHP 5.6
The questionnaire works (frontend), I've done several tests.
Now I want to export the results via csv - works.
But if click on "ANALYSIS", I see the first graphic (general), but no column or pie chart (analyse action: question based)
I've tried to switch the options via constants editor, but there's no result, s. screenshot
Uncaught ReferenceError: chart is not defined
