How to get "Process Details > Process Nodes" info for multiple instance in a (Custom?) Report

@georget518, The processHistory plugins will not help much. In the diagram that you have attached, the tab is about the details of the process nodes - with startTime, completionTime, priority and the duration. These details are not directly present in the HistoryRecord.
If you want those details, get an instance of the ProcessDiagram for the given processId.
The ProcessDiagram has methods to let you access the individual nodes in that Process. There are methods which will return you instance of RunTimeProcessNodes.

The RunTimeProcessNodes will give you the details of all the nodes in that process instance.
