The MK command positions a marker anywhere on the analyzer display. Use the PD command to rst place the pen down (except during reference-graphics mode.) Coordinates are specied in the current scale units, which are 0 to 1000 for the X and Y coordinates unless specied dierently with the SCALE command or with the DWINDOW command if a window is active. Use the MK command in conjunction with the PU and PD commands when the reference-graphics mode is o. During the reference-graphics mode, the marker is drawn at the item origin, as in the preceding example.
