WinCC 7.0 historical trends problem

[M_N]

Hi,

I've got problem with historical trends in WinCC 7.0 SP1?

When I display trend for period = 1..5 months everything is ok, but when I choose period > 5 months then only one vertical line is drawn. Tag logging is set to 13 months. Any ideas where should I look for soultion?

Best Regards
