**NAME**

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 byxmin,xmax,ymin,ymax,zminandzmaxin user-coordinate space is mapped into a box of world coordinate sizebasexbybaseybyheightso thatxminmaps to -basex/2,xmaxmaps tobasex/2,yminmaps to -basey/2,ymaxmaps tobasey/2,zminmaps to 0 andzmaxmaps toheight. The resulting world-coordinate box is then viewed by an observer at altitudealtand azimuthaz. This routine must be called beforeplbox3(3plplot) orplot3d(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. Whenaz=0, the observer is looking face onto the ZX plane, and asazis increased, the observer moves clockwise around the box when viewed from above the XY plane.
