An obscure abstract is shown below each graphic (it seems a "var_dump" instruction, like debug code).
e.g. :
array(7) { ["Quotidienne"]=> string(2) "19" ["Hebdomadaire"]=> string(2) "53" ["Mensuelle"]=> string(2) "20" ["Quelques fois par an"]=> string(2) "19" ["Jamais"]=> string(1) "4" ["Sans réponse"]=> string(1) "0" ["Non affiché"]=> int(0) }
This abstract isn't pretty : if user makes a screenshot, he'll have to manually erase it to have a pretty image.
It should be intersting to hide this abstract.
Thus, each response is displayed by "<<code>><<label>>(<<number>>) "<<label>>".
e.g. : AMensuellestring(9) "Mensuelle"
It should be interesting to display each response like : "<<label>>".
e.g. : "Mensuelle" |
