## 1.6.10 The -X -Y options

Using -X and -Y shifts the origin of the plot by (xoff,yoff) inches (Default is (1i,1i) for new plots1.5 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 quietly ignored).
