Plot

Plot [Data,Back,Resp,Sub]

By default this command displays the current data array onto the image device. The command prompts for a data min and max values. If a datum value matches your selected data min, then it is plotted with the minimum color index. Likewise a value corresponding to the data max value would be assigned the maximum color index, and values in between would be accordingly be allocated the in between color indices. Any values less than the data min are plotted with the minimum color index, and the maximum color index is used for values larger than data max. Thus extreme peaks are extreme valleys are often saturated.

This command is only valid if you have both read in a data file (with DAta command) and defined an image device (with CPD command).

examples

LEXTRCT> P        ! Display current data array on image device
 Display min and max (   363.    ,   869.    ):   ! default scale
PLT> Q            ! return to LEXTRCT prompt
LEXTRCT> P S      ! Display subtracted array on image device
 Display min and max (   363.    ,   869.    ): 100 200  ! new scale
PLT> Q            ! return to LEXTRCT prompt
