plw3d — Set up window for 3-d plotting

Synopsis

plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az)

Description

Sets up a window for a three-dimensional surface plot within the currently defined two-dimensional window. The enclosing box for the surface plot defined by xmin, xmax, ymin, ymax, zmin and zmax in user-coordinate space is mapped into a box of world coordinate size basex by basey by height so that xmin maps to -basex/2 , xmax maps to basex/2 , ymin maps to -basey/2 , ymax maps to basey/2 , zmin maps to 0 and zmax maps to height. The resulting world-coordinate box is then viewed by an observer at altitude alt and azimuth az. This routine must be called before plbox3(3plplot) or plot3d(3plplot). For a more complete description of three-dimensional plotting see the PLplot documentation.

Redacted form: plw3d(basex, basey, height, xmin, xmax, ymin, ymax, zmin, zmax, alt, az)

This function is examples 8,11,18,21.

Arguments

basex (PLFLT, input)
The x coordinate size of the world-coordinate box.
basey (PLFLT, input)
The y coordinate size of the world-coordinate box.
height (PLFLT, input)
The z coordinate size of the world-coordinate box.
xmin (PLFLT, input)
The minimum user x coordinate value.
xmax (PLFLT, input)
The maximum user x coordinate value.
ymin (PLFLT, input)
The minimum user y coordinate value.
ymax (PLFLT, input)
The maximum user y coordinate value.
zmin (PLFLT, input)
The minimum user z coordinate value.
zmax (PLFLT, input)
The maximum user z coordinate value.
alt (PLFLT, input)
The viewing altitude in degrees above the XY plane.
az (PLFLT, input)
The viewing azimuth in degrees. When az=0 , the observer is looking face onto the ZX plane, and as az is increased, the observer moves clockwise around the box when viewed from above the XY plane.
