Selective graphing and alerting

Is it possible to have a dashboard and alert that will show only the kubernetes volumes where inodes used >= a threshold of total available inodes. I want to do something like

timeseries graph and alert for volumes if

kubelet_volume_stats_inodes_used / kubelet_volume_stats_inodes > 85%

On the graph show

kubelet_volume_stats_inodes_used ) this might be better as stacked bar graph
kubelet_volume_stats_inodes ) because > 1 volume could breach threshold over the same time frame

I only want to see volumes that are breaching the threshold not all volumes because all volumes will just cluster the graph.
