Graphics display may be controlled by specifying the SOFT parameter on the command line of any ECHOMOP task. For example:
% ech_trace SOFT=device
(Note the CaSe is important on UNIX machines)
ECHOMOP also supports SOFT=NONE which disables all interactive graphics facilities and saves CPU time when such facilities are not required. The SOFT parameter should be set using
SOFT=NONE or SOFT=NULL
to disable ECHOMOP graphics.
Hard copy graphics is directed to /device/ using the parameter
HARD=device
The ech_plot task also provides the ability to re-direct the graphics output to any device during a run of the program. Typing >device at the ech_plot menu will direct future output to that device. Additionally, ech_plot can make one-off hard copies of the last plotted graph by typing ^ at the ech_plot menu prompt. Such plots will be output to the device specified using the hard parameter.
