1. Legos and Surfaces plot can be drawn in Polar, Cylindrical, Spherical and Pseudo rapidity coordinates.

   Note also:

2. The option UTIT allows to use ``user title'' on histogram. To define the title itself, the command TITLE should be used with the option U . Without this option TITLE define the global title.
