Looks fine to me, the dots showing 1 packet and 2 packets correspond with the actual packets in the capture. All the dots at the 0 line show intervals where no IGMP packets were received, i.e. the dot reflects the fact of 0 packets in that interval.
I suspect that your "previous versions" comment refers to the deprecated GTK UI, the graphing has been totally rewritten for the Qt UI, and this may have turned out with differences in displays.
If you feel the current graph is deficient, please raise a bug\enhancement request at the Wireshark Bugzilla.
