The Sherpa configuration variable (also called "state
object") sherpa.plot controls appearance of most (not
all) of the plots generated with the CPLOT, LPLOT, OPLOT and SPLOT
commands.
(The exceptions are those plots generated by the commands
LPLOT BACK; LPLOT DATA; LPLOT BACKFIT; LPLOT BFIT; LPLOT FIT; LPLOT
BDELCHI; LPLOT BRATIO; LPLOT BRESIDUALS; LPLOT DELCHI; LPLOT RATIO;
LPLOT RESIDUALS. For these commands, other configuration variables
control the plots appearance.)
