Coordinate Systems

All plot specifications requires a coordinate system. By default, rectangular (Cartesian) coordinates are used. This can be changed to polar coordinates by using .gg.coords.polar (see .qp.s.coord).

.gg.coords.cube

3D coordinate system

3D points are plotted via orthographic projection onto a 2D plane, which is tangential to a point on the unit sphere defined by 2 angles, the azimuth, and the altitude.

The azimuth is the angle between the point and the X axis along the X-Y plane. The altitude is the angle between the point and the X-Y plane. For more about azimuth/altitude, see: https://en.wikipedia.org/wiki/Azimuth

Parameter(s):
