|
* This function displays the report by question.
|
|
*
|
|
* It displays a table with all the options of the question and the number of users who have answered positively on the option.
|
|
* The number of users who answered positive on a given option is expressed in an absolute number, in a percentage of the total
|
|
* and graphically using bars
|
|
* By clicking on the absolute number you get a list with the persons who have answered this.
|
|
* You can then click on the name of the person and you will then go to the report by user where you see all the
|
|
* answers of that user.
|
|
*
|
|
* @param array All the survey data
|
|
* @return string html code that displays the report by question
|
|
* @todo allow switching between horizontal and vertical.
|
|
* @todo multiple response: percentage are probably not OK
|
|
* @todo the question and option text have to be shortened and should expand when the user clicks on it.
|
|
* @todo the pagebreak and comment question types should not be shown => removed from $survey_data before
