-–X and -–Y shift origin of plot by (xoff,yoff) inches (Default is (1,1) for new plots1.3 and (0,0) for overlays (-O)). By default, all translations are relative to the previous origin (see Figure 1.11). Absolute translations (i.e., relative to a fixed point (0,0) at the lower left corner of the paper) can be achieve by prepending ``a'' to the offsets. Subsequent overlays will be co-registered with the previous plot unless the origin is shifted using these options. The offsets are measured in the current coordinates system (which can be rotated using the initial -–P option; subsequent -–P options for overlays are ignored).
