Description
plmvorg moves the origin (the position (0,0)) of the user units coordinate system to the position (x,y) in the current user units coordinate system (plmvorg).Examples
The following program draws axes, then moves the origin and plots the same axes again; as the axes cross in the origin (that is: in the point (0,0)) in millimeters, the new axes are shifted with respect to the initial axes. Finally, a dot is plotted in the new coordinate system, before as well as after moving the origin with plmvorgm.plinit PS plmvorg A4 50 50 "" "" plaxes 100 100 200 200 70 70 "" "" "initial coordinate system" plmvorg 110 115 plaxes 100 100 200 200 70 70 "" "" "after plmvorg(110,115)" pldot 150 150 2 plmvorgm 10 10 pldot 150 150 2 plframe 5 3
