title: Why does Gitlab do not show a project network graph and other graphs for my imported repo?
body: <p>I have migrated cvs repo with cvs2svn240 and git fast-import1834 into a git repository. Also I have installed Gitlab53 and imported my git repo. So I can browse through files, add users and so on. Everything works fine. The only thing is that I always get blank graph pages.</p>
  
  <p>System: RHEL63, 65GB RAM, 4 CPU cores.
  Git-Repo: 2,8 GB (bare).</p>
  
  <p>I have not yet create new commits on the repo, it is still in after migration state. But I think it should show graphs based on the current repo data.</p>
  
  <p>Where could be my problem?</p>
