I set up a 3D coordinate system and a projection with range=[-7.,7] & az=40 & ax=35 ;, say surface,dist(4),/nodata,/save,xran=range,yran=range,zran=ran ge,$ ax=ax, az=az, $ xstyle=1+4,ystyle=1+4,zstyle=1+4 and then I plot in it with plotS. The x, y and z axes are equivalent and in the same units, (say, meters) so I want the resulting postscript to be a true projection (with a known scale factor) of this 3D field. How do I achieve that? Thanks for any pointers, Kristian Kjær
