demo project to reproduce the issue

Axis.Logarithmic := True crashes when Axis.Minimum < 0 even if Axis.AutomaticMinimum is True. It is possible to keep the same values for Axis.Minimum with the workaround. I think that with automatic min/max for axis, Logarithmic := True should work.

workaround:
Axis.AutomaticMinimum := False; 
Axis.Minimum := 0.0000001; 
Axis.Logarithmic := True; 
Axis.AutomaticMinimum := True;
