Currently using SonarQube 7.2 LGPL v3 Community. Branching has not been provided in community edition,it is a paid plugin for developer addition so that is not an option.
I simply want to see LOC of two projects as a chart.
Help would be greatly appreciated.
There is no such feature out of the box in SonarQube. You can use measures web API (example here) to retrieve the metrics you want and create the chart yourself for example in a spreadsheet.
