DCL:GRPH1:Summary:3-D Normalization Transformation

1.5.1 Types of Coordinate Systems

The following types of coordinates exist as user-defined coordinate systems (UC), and the user selects one by specifying the function number.

Number
1	Rectangular Coordinate
2	Cylindrical Coordinate
3	Spherical Coordinate

In contrast to 2-D coordinate systems, logarithmic axes are specified in 3-D systems with the log switch (see later section) and not by the function number.
