AHELP for CIAO 4.9 Sherpa v1


Context: contrib


The plot preferences for radial or elliptical profiles of the source model for imaging data.




The get_source_prof_prefs() command returns the preferences for plots created by the prof_source() command. Changing the values will not change existing plots, only new plots created after the change was made. For example

sherpa> get_source_prof_prefs()["xlog"] = True

will cause any new plots to use logarithmic scaling for the X axis. A list of all the preferences is given below.

Loading the routine

The routine can be loaded into Sherpa by saying:

from sherpa_contrib.profiles import *

Plot defaults

The following table lists the allowed keys and values for the object returned by get_source_prof_prefs().

Key Allowed values
xlog False, True
ylog False, True
linecolor Any valid ChIPS color (e.g. "red")
linethickness 0.5 to 10
linestyle chips_solid, chips_dot, chips_noline, chips_longdash, chips_shortdash, chips_dotlongdash, chips_dotshortdash, chips_shortdashlongdash
symbolstyle chips_circle, chips_cross, chips_diamond, chips_none, chips_plus, chips_square, chips_point_type, chips_uptriangle, chips_downtriangle
symbolcolor Any valid ChIPS color (e.g. "red")
symbolfill False, True
symbolsize 1 to 100


sherpa> prof_source()
sherpa> log_scale()
sherpa> prefs = get_source_prof_prefs()
sherpa> prefs["xlog"] = True
sherpa> prefs["ylog"] = True
sherpa> prof_source()

The preferences are set so that both the x and y axes should be drawn using log scaling. Setting the get_source_prof_prefs values only affects plots made after the change; to change an existing plot you need to use ChIPS commands such as log_scale() and linear_scale().


See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
