Synopsis
The plot preferences for radial or elliptical profiles of the residuals (data - model) to imaging data.
Syntax
get_resid_prof_prefs()
Description
The get_resid_prof_prefs() command returns the preferences for the residuals in plots created by the prof_resid() and prof_fit_resid() commands. Changing the values will not change existing plots, only new plots created after the change was made. For example
sherpa> get_resid_prof_prefs()["xlog"] = True
will cause any new plots to use logarithmic scaling for the X axis.
Loading the routine
The routine can be loaded into Sherpa by saying:
from sherpa_contrib.profiles import *
Example
sherpa> prof_resid() sherpa> plt.xscale('log') ... sherpa> prefs = get_resid_prof_prefs() sherpa> prefs['xlog'] = True sherpa> prefs['xaxis'] = False sherpa> prof_resid()
The preferences are set so that the x axis should be drawn using log scaling and no line is drawn at y=0. Setting the get_resid_prof_prefs values only affects plots made after the change; to change an existing plot you need to use Matplotlib commands such as xscale().
Bugs
See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
