      Add a "Survey" activity to a course.
      Choose:

      • Name: whatever you like
      • Survey type: "COLLES (Actual)"
        Save and display
        Add a random answer
        Submit your answer pushing the button "Click here to continue"

      From "Administration" block choose "Response report" and then the sub-item "Question"
      You are supposed to get a page with a 4x6 + 1 graphs
      but they are not displayed leaving in the page only links without corresponding graphs.

      If you look at the html source code of the page you understand that the graphs are expected from an URL like:
      http://path/to/your/moodle/test/site/mod/survey/graph.php?id=76&qid=1&group=0&type=question.png

      If you call that link in a different browser page
      you get a long list of:

      ( ! ) Notice: Trying to access array offset on value of type null in path/to/your/moodle/test/site/lib/graphlib.php on line 310
