No colored lines in the statistics

[unmerged(5083)]

If I press F6 and open my "Logbook" I will not see anymore the colered lines in the statistics. The competition between the major nations is not any longer visible. (No graphs in the statistics)

I have the same problem and have posted about it in the general forum (probably should have used this one).
I think that it is a general problem and someone suggested that the graps only show stats since you last loaded, it would be nice to get some info on this...

I've experienced the same thing. It's reported as a bug, check this link:

I hope it gets corrected in the next patch.
