From Mathematica's help

"LogGamma[z] is analytic throughout the complex z plane, except for a single branch cut discontinuity along the negative real axis. Log[Gamma[z]] has a more complex branch cut structure."

Thanks. But, I need more practical help. Like using formulas and functions and graphs.

maybe this will fulfill your needs.

Then, (if I understood correctly) for $$\displaystyle z \in \mathbb{R}$$ they are the same thing???
