[FIX] web: bar chart no crazy with 2 group by

In 3d2ca8104e4 some change were introduced to the graph view.

But part of it had no sense when displaying data over 2 group by.

eg. if the first level has 2 groups (2018, 2019) and each second level 2
    groups (Done,Cancelled), we could have:
     2018/Done: 0
     2018/Cancelled: 5
     2019/Done: 8
     2019/Cancelled: 9
    this gives us two main groups [2018: 5] / [2019: 17], the code
    remove the 2018 because [2018/Done] is 0 so we have something odd
    with columns not in order, and in stacked bar chart some part of
    a bar at the wrong offset
