DRAWING 3-DIMENSIONAL PLOTS


Not available on UNIX



3-dimensional cartesian coordinates are supported. An element in
space may be defined by the parameters XMIN, XMAX, YMIN, YMAX,
ZMIN and ZMAX of the commands GDISP, GPLOT, GOVER, or GPRESET.
It is projected on the screen in parallel projection.
The viewing direction is given by the parameters THETA and PHI
of the commands mentioned above.
It is recommended to use a cubic element in space and the parameters
NOAXIS and FORMAT(1). The parameters ZMIN and ZMAX must be specified!


Plotting data in 3-dim coordinates.

   An additional row with Z-data has to be given:

   H:   X     Y,LT11    Z
        0.1    3.5      4.2
        0.4    8.9      5.9
 

Drawing graphic elements in 3-dim coordinates.

   Some graphic elements are defined for 3-dim coordinates.
 
   E: POINT(x,y,z);
   E: LINE(x-first,y-first,z-first,x-last,y-last,z-last,line-mode);
   E: ARLINE(x1,y1,z1,x2,y2,z2,size of arrow, opening angle, line-mode);
   E: TRIANGLE(x1,y1,z1,x2,y2,z2,x3,y3,z3,line-mode);
   E: CIRCLE(x-center,y-center,z-center,from angle,to angle,
             theta of plane,phi of plane,radius,line-mode);
   E: SHIFT(x-shift,y-shift,z-shift);

   Invisible parts of the figures are not hidden.
 

Writing a text in 3-dim coordinates.

   For writing a text in 3-dim coordinates,
   the z coordinate has to be specified:

   W: text / x(10) y(30) z(90) s(8)
