[SOLVED] Some help about the code in order to evolve Gantt chart

(I don't know if I should post this in ask question or submit evolution ?)
Hello everyone,

As part of an internship I have to evolve the Gantt chart by adding the possibility to order Gantt chart per ressources. (planning per ressources is not what I want)

I've already look in many files and read the code, but projeqtor code is oversized. So I'd like to ask for your help Babynus, or anyone who know the architecture of the source code.
Actually the files who seem the most interesting are "jsonResourcesplanning.php" , "SqlElement.php".

I'd like to find the array that stock the SQLrequest that go find the ressources in DB for each activity in a project and try to order this array per ressources.
Actually my notion of SQL request are naive, I mean I write the request completly, but I don't find any naive request of this kind. Like I'd like to find a request that say :
"SELECT idResource FROM activity (and I would add ORDER BY id resource) ;" But of course this is not that easy.
I would understand how the request are made and/or where. It would be very helpfull because I could understand how the exchanges with DB works.

Can you help me please ?

Thank you for responding.
here is the planning

I suspected it , thank you for your help.

I added this in config/parameters.php (I added it in view/parameter.php first time..) then I checked the log and I don't see trace of query, then I checked all the directory but nothing. Can the trace be somewhere else than in the log ? I'm actually on v6.5.6

Done and it's the good one
parameters?php :
<?php
$parametersLocation = '../files/config/parameters.php';

I don't understand why it's doing nothing
