The lego plot shows stacks of energy seen in the calorimeter towers. The stacks are positioned on the surface spanned by η (in radians) and φ (in degrees).
Parameters
View
Select the data type, choice between:
Calo (default)
LVL1TriggerTower

ET Axis Height
Set the maximum height of the ET axis in GeV.
0 = auto sets height to height of tallest calo tower or if no calo information is present then the tallest AOD tower is used.
φ Cells
Set the number of bins in φ.
η Cells
Set the number of bins in η.
Lego Cut
Set the minimum energy for lego bars to be drawn.

The Lego Projection Menu (see 3.3.2 Projection Menus)
These options are to aid with selecting useful rotations which can also be achieved by using the rotation option in ZMR (4.1 Zoom/Move/Rotate (ZMR)).
View normal - Sets the viewing angle to the default.
View from above - Sets the viewing angle to view from above so reduces the Et axis size.
View ET v η - Sets the viewing angle so that the plot is ET v η.
View ET v φ - Sets the viewing angle so that the plot is ET v φ.
