B.10 plot2sphere: Draws a sphere plot

plot2sphere draws plots in an isotropic 3-dimensional space using spherical polar coordinates. The plotting volume is a cube, which is viewed from the outside and usually bounded by a wire frame annotated by Cartesian coordinates. This viewing cube is not necessarily centered on the coordinate origin.

This plotting geometry is like that used by plot2cube, but the coordinate unit size is always the same in the three dimensions, and the coordinates are specified differently.

Positional coordinates are specified as lon, lat, r triples, e.g.:

   plot2sphere layer1=mark in1=survey.fits lon1=RA lat1=DEC r1=REDSHIFT

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, link2, mark2, label, contour.
