Looks like there has been a couple changes in Grafana that broke our plugin.
1. Hidden series are no longer passed to the datasource by default.
2. If the series values we return leads with 'NaN' the whole series is ignored.
Fixed in develop with:

After updating Grafana to Version 6.3.2 today approximately 3/4 of my OpenNMS-based graphs are broken. It seems that this happens when I use expressions and hide the original metrics in the Query Editor. For me it looks like that when I hide a metric I'm not longer allowed to use it in an expression. My current workaround is to use v6.2.5:
# apt install grafana=6.2.5 # apt-mark hold grafanaAnother workaround is not to hide the metrics and use "Add series override" to set for the metrics Lines=false, Line fill=0, Legend=false
