FishEye does not currently support LoC stats or charts for Mercurial repositories.
Add in support for these.
Note we had support in 2.3, but it was based on some code which worked really well for "linear" VCSs like SVN and CVS, but it was broken for DAG based commit graph systems like Mercurial (and Git:
CRUC-4524). We are working on a better solution, but vote here to increase it's priority.
