Hello,
if you're getting these gaps on many devices it may be that you added one that is responding slowly to snmp queries.
This thing happened to me when I added a couple of nexus 7000 with a old firmware, all the other devices graphs appeared in this way.
Try removing the last device you added, or increase their snmp timout.

You may also see high CPU on those devices.

Hope this helps,

Stefano
