plot2cube: Draws a cube plot
plot2cube draws plots in a Cartesian 3-dimensional space.
The plotting volume is a cube,
which is viewed from the outside and usually bounded by
an annotated wire frame.
Positional coordinates are specified as
x, y, z triples,
e.g.:
plot2cube layer1=mark in1=sim.fits x1=XPOS y1=YPOS z1=ZPOS
Content is added to the plot by specifying
one or more plot layers using the
layerN parameter.
The N part is a suffix applied to
all the parameters affecting a given layer;
any suffix (including the empty string) may be used.
Available layers for this plot type are:
mark,
size,
sizexy,
xyzvector,
xyzerror,
link2,
mark2,
poly4,
mark4,
polygon,
label,
line3d,
contour,
spheregrid.
