Graph display problems

[makenfly]

Hi, we just connected our Fortigate router to our Zabbix server to moderate some Vlan activities but we're having some issues whit the graph display on our dashboard.

Theres some big holes in our graph and only when we zoom in to 1 min (minimum on the time (X) axis) that we can see the graph.

Does anyone know why?
